Subject: ath10k: print htt op_version upon driver boot

HTT version itself isn't sufficient to know what
HTT version given firmware blob uses. Hence print
the recently introduced HTT op version code.

While at it make the info string a bit more
consistent and clear.

Subject: ath10k: enable VHT for IBSS

Enable VHT support for IBSS, while mac80211/cfg80211 and
wpa_supplicant already support this.

In my test env, qca988x 2x2 I get:

(udp) ath10k-1 >>>> ath10k-2 (server) -  speed: 419 Mbits/sec
(tcp) ath10k-1 >>>> ath10k-2 (server) -  speed: 404 Mbits/sec

During tests I used wpa_supplicant (latest git version), which
already support IBSS VHT, and choose highest available BW. Also tested with
qca6174.

Subject: iwlwifi: mvm: rs: report last tx rate based on RSSI and caps

In scenarios where we haven't converged yet to a specific modulation
and rate it could be better to report to userspace the last tx rate
based on the STA capabilities and RSSI. This is important as sometimes
userspace displays the last tx rate as the link speed.
This avoids being presented with low legacy rates when rs just begins
its search or after an idle period in which it resets itself.

Subject: iwlwifi: mvm: handle RX MPDUs separately

There's no need to forward RX MPDUs to notification wait tests, nor
do we need to check them for firmware dump triggers, nor could they
be asynchronous. It's thus more efficient to handle them separately,
before going into the regular RX handlers.

This allows to ensure that we don't have races between them.
A user reported that stop_device was called twice upon
rfkill interrupt after suspend. When the interrupts are
enabled, and right after when we directly check the rfkill
state.

Subject: ath10k: Add a table to store hw specific values

This is to prepare ath10k to support newer chip set.
Values like CE_COUNT, MSI_ASSIGN_CE_MAX and
RTC_STATE_V_ON can be different for different
chips.

Subject: ath10k: Add hw register/values for QCA99X0 chip

This is to prepare the driver for QCA99X0 chip support.
This commit adds hw_params, hw register table and hw_values
table for QCA99X0 chip. Please note this is only a partial patch adding
support for QCA99X0, so the device id is not yet added to pci device
table.

Subject: ath10k: Copy Engine related changes for QCA99X0

QCA99X0 supports upto 12 Copy engines. Host and target
CE configuration table is updated to support new copy engine
pipes. This also fixes the assumption of diagnostic CE by making
CE_7 as the one instead of CE_COUNT - 1.

ath10k_pci_irq_msi_fw_mask() and ath10k_pci_irq_msi_fw_unmask()
non-99X0 specific till we get proper register configuration
to mask/unmask irq/MSI.

Subject: ath10k: Extend CE src desc flags for interrupt indication

QCA99X0 uses two new copy engine src desc flags for interrupt
indication. Bit_2 is to mark if host interrupt is disabled after
processing the current desc and bit_3 is to mark if target interrupt
is diabled after the processing of current descriptor.
CE_DESC_FLAGS_META_DATA_MASK and CE_DESC_FLAGS_META_DATA_LSB are based
on the target type.

There is more than 1 sec delay in getting response from target
through BMI in QCA99X0. Increase the BMI communication timeout
to 2*HZ to fix BMI failures.

Subject: ath10k: Add support for code swap

Code swap is a mechanism to use host memory to store
some fw binary code segment. Ath10k host driver allocates
and loads the code swap binary into the host memory and
configures the target with the host allocated memory
information at the address taken from code swap binary.
This patch adds code swap support for firmware binary.
Code swap binary for firmware bin is available in
ATH10K_FW_IE_FW_CODE_SWAP_IMAGE.

qca99X0 chip uses firmware version 10.4. Define a new macro
ATH10K_FW_WMI_OP_VERSION_10_4 for 10.4 firmware and include
in switch cases where ATH10K_FW_WMI_OP_VERSION_* is used
to avoid compilation error.

Subject: ath10k: include 10.4 fw specific wmi cmd and event ids

10.4 firmware wmi cmd and event id values are not exactly aligned
with previous firmware versions (main, 10.x, 10.2, etc). Add new
enum to define wmi cmd & event definitions for 10.4 firmware and
prepare wmi_10_4_cmd_map based on 10.4 firmware wmi cmd definitions.

wmi_cmd_map is extended to accommodate new wmi commands which are
exclusively available in 10.4 firmware.

Subject: ath10k: set 10.4 fw exclusive wmi cmd as unsupported for other fw
 versions

In fact, explicit assigned to ZERO for unsupported wmi commands
are not really needed. Global static variable will have ZERO by
default. However, just for better readability setting all wmi cmds
in non 10.4 firmware wmi mapping table as unsupported for wmi cmd
which are exclusively available only in 10.4 firmware.

Subject: ath10k: add 10.4 fw wmi vdev cmd ids

Include 10.4 firmware wmi vdev cmd id and make up wmi vdev map
table wmi_10_4_vdev_param_map and also update non 10.4 firmware
vdev cmd map table with newly added vdev cmd id specifically for
10.4 firmware as unsupported.

From 1c0929614ac429a32509307e790e813325562dc1 Mon Sep 17 00:00:00 2001
From: Raja Mani <rmani@qti.qualcomm.com>

Subject: ath10k: handle 10.4 fw wmi mgmt rx event

10.4 firmware wmi mgmt rx event format differs from non 10.4
firmware and changing existing wmi mgmt rx event parsing function
ath10k_wmi_op_pull_mgmt_rx_ev() for 10.4 would add more complex.

This patch adds new function to receive any wmi rx event from
10.4 firmware and also introduce new function to parse wmi mgmt
rx event.

In addition, fw main branch service rdy event parsing function
is linked in wmi ops table.

Subject: ath10k: adjust default peer limits if qcache enabled in 10.4 fw

10.4 firmware supports upto 512 clients when qcache feature is enabled.
Make adjustment on default max peer count, active peers, number of tid in
such case to meet qcache requirement. 10.4 fw has extra unit info flag
NUM_UNITS_IS_NUM_ACTIVE_PEERS which is also handled in this patch.

Subject: ath: DFS - limit number of potential PRI sequences

In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.

Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.

This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.

Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

Subject: wil6210: restart AP upon change in privacy settings

privacy settings might change while AP is running.
Inside wil_cfg80211_change_beacon(), detect change
in privacy settings and handle it by stopping and
re-starting the AP.
Firmware cannot handle on-the-fly privacy settings
change and so AP restart is required.

Subject: ath10k: enhance swba event handler to adapt different size tim bitmap

Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.

Subject: ath10k: handle 10.4 firmware wmi swba event

10.4 firmware swba event payload has space to accommodate upto
512 client traffic indication info & one p2p noa descriptor.
It's is not matching with exiting swba event format defined for
non 10.4 firmware. Non 10.4 firmware swba event format is designed
to support only upto only 128 client and four p2p notice of absence
descriptor.

following changes are done in this patch to enable ath10k to handle
10.4 firmware swba event,

 - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba
   event in 10.4 wmi rx handler.

 - add 10.4 specific swba event structure wmi_10_4_host_swba_event.

 - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse
   10.4 swba event.

 - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station
   power save state.

Subject: ath10k: enable vdev and peer related operations for 10.4 fw

Most of existing vdev and peer related functions (vdev create,
vdev delete, vdev start, peer create, peer delete, peer flush, etc)
are reusable for 10.4 firmware. Link those general vdev and peer
functions to 10.4 wmi function table.

Existing general pktlog enable/disable, dbglog configuration functions
are reusable for 10.4 and add them also in wmi function table.

Also handle few wmi events (sevice rdy, echo, dbg msg, tbtt offset
update, dbg print) in ath10k_wmi_10_4_op_rx(). wow event is not
applicable in 10.4 firmware, have it under not implemented print.

Subject: ath10k: add scan support for 10.4 fw

Existing non 10.4 firmware scan related events and commands are
matching with 10.4 firmware (except chan info event). Link general
start scan,stop scan, scan channel list configuration functions
to 10.4 wmi function table and add a new handler to parse 10.4
specific chan info event.

10.4 firmware has extra scan completion reason
WMI_SCAN_REASON_INTERNAL_FAILURE and new scan event
WMI_SCAN_EVENT_FOREIGN_CHANNEL_EXIT compared to previous firmware
versions. These things are added in respective enum.

Subject: ath10k: configure frag desc memory to target for qca99X0

Pre qca99X0 chipsets follows the model where dynamically allocate
memory for frag desc on getting new skb for TX. But, this is not
going to be the case in qca99X0. It expects frag desc memory to be
allocated at boot time and let the driver to reuse allocated memory
after every TX completion. So there won't be any dynamic frag memory
memory allocation in qca99X0 during data transmission.

qca99X0 hardware doesn't need fragment desc address to be programmed
in msdu descriptor for every data transaction. It needs to know only
starting address of fragment descriptor at the time of the boot.
During data transmission, qca99X0 hardware can retrieve corresponding
frag addr by adding programmed frag desc base addr + msdu id.

Allocate continuous fragment descriptor memory (same size as number of
descriptor) at the time of target initialization and configure allocated
dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.

How this is allocated continuous memory is going to be used is not
covered in this patch. It just allocates memory and hand over to firmware.
If we don't do it at init time, qca99X0 will stall when firmware tries
to do TX.

Subject: mlx4: TCP/UDP packets have L4 hash

Mellanox driver has the knowledge if rxhash is a L4 hash,
if it receives a non fragmented TCP or UDP frame and
NETIF_F_RXCSUM is enabled on netdev.

ip_summed value is CHECKSUM_UNNECESSARY in this case.

Subject: ifb: add multiqueue operation

Add multiqueue capabilities to ifb netdevice.

This removes last bottleneck for ingress when mq qdisc can be used
to shard load from multiple RX queues on physical device.

Tested:

# netem based setup, installed at receiver side
ETH=eth0
IFB=ifb10
EST="est 1sec 4sec" # Optional rate estimator
RTT_HALF=2ms
#REORDER=20us
#LOSS="loss 1"
TXQ=8

ip link add ifb10 numtxqueues $TXQ type ifb
ip link set dev $IFB up

tc qdisc add dev $ETH ingress 2>/dev/null

tc filter add dev $ETH parent ffff: \
   protocol ip u32 match u32 0 0 flowid 1:1 \
	action mirred egress redirect dev $IFB

tc qdisc del dev $IFB root 2>/dev/null

tc qdisc add dev $IFB root handle 1: mq
for i in `seq 1 $TXQ`
do
 slot=$( printf %x $(( i )) )
 tc qd add dev $IFB parent 1:$slot $EST netem \
	limit 100000 delay $RTT_HALF $REORDER $LOSS
done

Subject: hv_netvsc: Add support to set MTU reservation from guest side

When packet encapsulation is in use, the MTU needs to be reduced for
headroom reservation.
The existing code takes the updated MTU value only from the host side.
But vSwitch extensions, such as Open vSwitch, require the flexibility
to change the MTU to different values from within a guest during the
lifecycle of a vNIC, when the encapsulation protocol is changed. The
patch supports this kind of MTU changes.

Subject: cxgb4: Don't use entire L2T table, use only its slice

The driver was retrieving the parameters for the bounds of its
slice of the L2T from the firmware and then throwing those away and
using the entire table. This corrects that problem.

Subject: cxgb4vf: Fix check to use new User Doorbell mechanism

If we don't have access to the new User GTS (T5+), use the old doorbell
mechanism; otherwise use the new BAR2 mechanism.

Subject: neterion: s2io: Use module_pci_driver

Use module_pci_driver for drivers whose init and exit functions
only register and unregister, respectively.

A simplified version of the Coccinelle semantic patch that performs
this transformation is as follows:

@a@

-static f(...) { return pci_register_driver(&x); }

@b depends on a@
identifier e, a.x;
statement S;
@@
-static e(...) {

-DBG_PRINT(INIT_DBG,"S");
- }

@c depends on a && b@

-module_init(f);

@d depends on a && b && c@
identifier b.e, a.x;
declarer name module_exit;

-module_exit(e);

Subject: be2net: query FW to check if EVB is enabled

The current code assumes that bridge functionality (EVB) in the adapter
is enabled only when SR-IOV is enabled. This is not always true.
This patch uses the GET_HSW_CONFIG FW cmd to query this from the FW.

Subject: be2net: fix wrong return value in be_check_ufi_compatibility()

In the commit a6e6ff6eee12f3e
("be2net: simplify UFI compatibility checking"), a return value of "-1"
was incorrectly used in place of "false". This patch fixes it.

Subject: be2net: make the RX_FILTER command asynchronous

This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues
this cmd and doesn't wait for a completion from the FW. If the FW/adapter
is in an error state, this change helps in not holding up the rtnl_lock
and keeping bottom halves disabled while the driver timesout waiting for
a response from the FW.

Subject: be2net: make SET_LOOPBACK_MODE cmd asynchrounous

The SET_LOOPBACK_MODE command is always issued from ethtool only in a
process context. So, while waiting for the cmd to complete, the driver
can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done
by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns
only after the cmd completes while the MCCQ is locked).

Subject: ath10k: fix QCA61X4 boot up

commit a521ee983d312db7 ("ath10k: Add new reg_address/mask to hw register
table") broke QCA61x4 support by providing wrong
fw_indicator_address, which should have been 0x0003a028 instead of 0x00009028.

User experience was a failing boot up sequence (crashing device during
initialization):

[  181.663874] ath10k_pci 0000:02:00.0: enabling device (0000 -> 0002)
[  181.664787] ath10k_pci 0000:02:00.0: pci irq msi-x interrupts 8 irq_mode 0 reset_mode 0
[  181.688886] ath10k_pci 0000:02:00.0: device has crashed during init
[  181.688897] ath10k_pci 0000:02:00.0: failed to wait for target after cold reset: -70
[  181.688902] ath10k_pci 0000:02:00.0: failed to reset chip: -70
[  181.689774] ath10k_pci: probe of 0000:02:00.0 failed with error -70

Fix it by updating the address with correct value.

Subject: ath10k: limit multi-vif ps more aggresivelly

Further testing proved that multi-channel AP+STA
on QCA6174 with RM.2.0-00088 should have powersave
force-disabled to avoid beacon misses/skipping on
either side which in turn could disrupt
communication.

Since AP never has arvif->ps don't even bother
checking it. Other combinations may be broken as
well so disallow powersave with multivif outright
unless firmware advertises otherwise.

Subject: ath10k: fix hw roc expiration notifcation

The expiration function must not be called when
roc is explicitly cancelled by mac80211. However
since fcf9844636be ("ath10k: fix hw roc
expiration") the notification was never sent when
roc actually expired.

This fixes some P2P connection setup issues.

Subject: ath10k: update vdev ps state on start

Psmode can be forcefully enabled when vdev isn't
started. It isn't guaranteed that mac80211 will
re-issue psmode setting after vdev is started
unless actual bss_conf.ps value has changed.

Even if this doesn't fix any problems now it may
prevent future breakage.

Subject: ath10k: fix per-vif queue locking

Whenever any vdev was supposed to be paused all Tx
queues were stopped (except offchannel) instead of
only these associated with the given vdev.

This caused subtle issues with
multi-channel/multi-vif scenarios, e.g.
authentication of station vif could sometimes fail
depending on fw tx pause request timing.

Concurrent AP/GO operation on different channels

it's better to remove it from being advertised.

Also tune the way station and p2p client interface
limits are expressed to allow station + 2x p2p
client or station + p2p client + p2p go.

HW_PHY_OFF_LOOP_DELAY (HZ / 5000) which always evaluated to 0. Clarified
by Stanislav Yakovlev <stas.yakovlev@gmail.com> that it should be 50
milliseconds thus fixed up to msecs_to_jiffies(50).

Subject: ath9k: DFS - consider ext_channel pulses only in HT40 mode

The chip reports radar pulses on extension channel
even if operating in HT20 mode. This patch adds a
sanity check for HT40 mode before it feeds pulses
on extension channel to the pattern detector.

Subject: ath9k: DFS - add pulse chirp detection for FCC

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Since the driver can dynamically enable/disable FD ATR and SB features,
these stats help keep track of the current state and along with
fd_flush count provide a means to debug what could be going on
with the flow director filters. This will take away the need for
being verbose in our debug logs with respect to FD.

information needed to support Flex-10 configurations. This patch adds new
fields to the i40e_hw_capabilities structure and updates
i40e_parse_discover_capabilities functions to extract them from the AQ
response. Naming convention has changed to use flex10 mode instead of
existing mfp_mode_1.

Subject: i40evf: Allow for an abundance of vectors

The driver currently only maps TX and RX queues to a single MSI-X vector
per queue pair if there are exactly enough vectors for this.
Unfortunately, if we have too many vectors it will fail and allocate
queues to vectors in a suboptimal manner. Change the condition check to
allow for excess vectors. In this case, the extras just won't be used.

Subject: i40e: ignore duplicate port VLAN requests

If user attempts to set a port VLAN on a VF that already has the same
port VLAN configured, the driver will go through a completely
unnecessary flurry of filter removals and filter adds. Just check for
this condition and return success instead of doing a bunch of busywork.

Subject: i40e: Remove incorrect #ifdef's

This patch removes some #ifdef's that should not be there. They
were stopping code that is needed from being compiled in.

With these #ifdef's removed, changes are needed in the driver
to fix some compile errors: adding missing parameters to
the definition of ndo_bridge_setlink and a ndo_dflt_brige_getlink call.

Subject: i40e: correctly program filters for VFs

MAC filters for VFs were being programmed with 0 for the VLAN value when
there was no VLAN assigned. This is incorrect and actually assigns the
VF to VLAN 0. Instead, we must use -1 to indicate that no VLAN is in
use. This change programs the filters correctly and gets rid of a bogus
error message when setting a port VLAN on an active VF.

Subject: i40e: do a proper reset when disabling a VF

The VF disable code was just whanging on the reset bit without properly
cleaning up the VF, which would leave the VF in an indeterminate state
from which it could not recover. Fix this by notifying the VF and then
by calling the normal VF reset routine.

When a VF is disabled, there is no way for it to recover until either
the PF driver is reloaded or SR-IOV is disabled and enabled. To correct
this, enable the VF after a successful reset.

Subject: i40evf: don't delete all the filters

Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin
queue, the driver would (accidentally) end up with a varying number of
functional filters.

Correct this logic so that MAC filters are added and removed correctly.
Add a check for the driver's "hardware" MAC address so that this filter
doesn't get removed incorrectly.

Subject: i40evf: add MAC address filter in open, not init

During close, all of the MAC filters are cleared, so the driver would be
unable to receive unicast packets after being closed and reopened.

Add the adapter's "hardware" MAC address filter in open, not init. This
ensures that the correct filter is present each time.

Subject: i40e/i40evf: Add support for pre-allocated pages for PD

The i40e_add_pd_table_entry() routine is being modified to handle both
cases where a backing page is passed and where backing page is allocated
in i40e_add_pd_table_entry().

For PBLE resource management, it is more efficient for it to manage its
backing pages. For VF, PBLE backing page addresses will be send to PF
driver for PBLE resource.

The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and
free only ones which were allocated in i40e_add_pd_table_entry().

Subject: gianfar: Bundle Rx allocation, cleanup

Use a more common consumer/ producer index design to improve
rx buffer allocation.  Instead of allocating a single new buffer
(skb) on each iteration, bundle the allocation of several rx
buffers at a time.  This also opens the path for further memory
optimizations.

Remove useless check of rxq->rfbptr, since this patch touches
rx pause frame handling code as well.  rxq->rfbptr is always
initialized as part of Rx BD ring init.
Remove redundant (and misleading) 'amount_pull' parameter.

Subject: gianfar: Fix and cleanup rxbd status handling

There are several (long standing) problems about how the status
field of the rx buffer descriptor (rxbd) is currently handled on
the error path:
- too many unnecessary 16bit reads of the two halves of the rxbd
status field (32bit), also resulting in overuse of endianness
convesion macros;
- "bdp->status = RXBD_LARGE" makes no sense, since the "large"
flag is read only (only eTSEC can write it), and trying to clear
the other status bits is also error prone in this context
(most of the rx status bits are read only anyway).

This is fixed with a single 32bit read of the "status" field,
and then the appropriate 16bit shifting is applied to access
the various status bits or the rx frame length. Also corrected
the use of the RXBD_LARGE flag.

Additional fix:
"rx_over_errors" stat is incremented instead of "rx_crc_errors"
in case of RXBD_OVERRUN occurrence.

Subject: gianfar: Use ndev, more Rx path cleanup

Use "ndev" instead of "dev", as the rx queue back pointer
to a net_device struct, to avoid name clashing with a
"struct device" reference.  This prepares the addition of a
"struct device" back pointer to the rx queue structure.

Remove duplicated rxq registration in the process.
Move napi_gro_receive() outside gfar_process_frame().

Subject: gianfar: Add paged allocation and Rx S/G

The eTSEC h/w is capable of scatter/gather on the receive side
too if MAXFRM > MRBLR, when the allowed maximum Rx frame size
is set to be greater than the maximum Rx buffer size (MRBLR).
It's about time the driver makes use of this h/w capability,
by supporting fixed buffer sizes and Rx S/G.

The buffer size given to eTSEC for reception is fixed to
1536B (must be multiple of 64), which is the same default
buffer size as before, used to accommodate standard MTU
(1500B) size frames.  As before, eTSEC can receive frames of
up to 9600B.  Individual Rx buffers are mapped to page halves
(page size for eTSEC systems is 4KB).  The skb is built around
the first buffer of a frame (using build_skb()).  In case the
frame spans multiple buffers, the trailing buffers are added
as Rx fragments to the skb.  The last buffer in frame is marked
by the L status flag.  A mechanism is in place to reuse the pages
owned by the driver (for Rx) for subsequent receptions.

Supporting fixed size buffers allows the implementation of Rx S/G,
which in turn removes the memory pressure issues the driver had
before when MTU was set for jumbo frame reception.
Also, in most cases, the Rx path becomes faster due to Rx page
reusal, since the overhead of allocating new rx buffers is removed
from the fast path.

Subject: hv_netvsc: Add close of RNDIS filter into change mtu call

The current change mtu call only stops tx before removing RNDIS filter.
In case ringbufer is not empty, the rndis_filter_device_remove() may
hang on removing the buffers.

This patch adds close of RNDIS filter before removing it, also a
gradual waiting loop until the ring is empty. The change_mtu hang
issue under heavy traffic is solved by this patch.

Subject: ibmveth: add support for TSO6

This patch adds support for a new method of signalling the firmware
that TSO packets are being sent. The new method removes the need to
alter the ip and tcp checksums and allows TSO6 support.

Subject: rocker: Handle protodown notifications.

protodown can be set by user space applications like MLAG on detecting
errors on a switch port. This patch provides sample switch driver changes
for handling protodown. Rocker PHYS disables the port in response to
protodown.

Subject: mac80211: don't store napi struct

When introducing multiple RX queues, a single NAPI struct will not
be sufficient. Instead of trying to store multiple, simply change
the API to have the NAPI struct passed to the RX function. This of
course means that drivers using rx_irqsafe() cannot use NAPI, but
that seems a reasonable trade-off, particularly since only two of
all drivers are currently using it at all.

While at it, we can now remove the IEEE80211_RX_REORDER_TIMER flag
again since this code path cannot have a napi struct anyway.

Subject: freescale: remove incorrect copied comment

The comment in question is word-for-word copied from ixgbe, and clearly
has no meaning in freescale's driver. (it even says 'return an error'
when the code clearly does not). Remove the comment as it is obviously
incorrect and not applicable to the code as it is today.

Subject: igb: Pull timestamp from fragment before adding it to skb

This change makes it so that we pull the timestamp from the fragment before
we add it to the skb.  By doing this we can avoid a possible issue in which
the fragment can possibly be less than IGB_RX_HDR_LEN due to the timestamp
being pulled after the copybreak check.

While making this change I realized we could also pull the rest of the
igb_pull_tail function into igb_add_rx_frag since in the case of igb,
unlike ixgbe, we are able to unmap the entire buffer before calling
add_rx_frag so merging the two allows for sharing of code between the two
merged functions.

This change folds the ixgbevf_pull_tail call into ixgbevf_add_rx_frag.  The
advantage to doing this is that the fragment doesn't have to be modified
after it is added to the skb.

Subject: ixgbe: Don't report flow director filter's status

For two reasons I want to disable this:
1. Not any part actually check the report status(Alexander Duyck)
2. To report hash value of a packet to stack,
   RSS -> 32bits hash value
   Perfect match fdir filter -> 13bits hash value
   Hashed-based fdir filter -> 31bits hash value

   fdir filter might hash on masked tuples for IP address,
   so it's still not desirable for usage.

So for now, just stick to RSS 32bits hash value.

e1000_check_for_link_media_swap() checks PHY page 0 for copper and PHY

happened too soon, before e1000_check_for_link_82575() is executed, and
link on fiber (other) was never detected. Check for link while still on

Subject: enic: add adaptive coalescing intr for intx and msi poll

Adaptive interrupt coalescing is available for msix. This patch adds the support
for msi poll. Interface for adaptive interrupt coalescing is already added in
driver. We just did not enable it for legacy intr & msi.

enic_calc_int_moderation() & enic_set_int_moderation() are defined as static
after enic_poll. Since enic_poll needs it, move both of these function
definitions above enic_poll. No change in functionality.

Subject: enic: allow adaptive coalesce setting for msi/legacy intr

* Allow setting of adaptive coalescing setting for all types of interrupt.

* In msi & legacy intr, we use single interrupt for rx & tx. In this case
  tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
  Do not display tx_coal values for msi/intx. And do not allow user to set
  this as well.

* Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
  For other values, driver does not return error. So ethtool succeeds for
  unsupported values. Introduce enic_coalesce_valid() function to validate
  the coalescing values.

* If user requests for coalesce value greater than what adaptor supports,
  driver uses the max value. We should at least log this.

Subject: rocker: forward packets to CPU when port is joined to openvswitch

Teach rocker to forward packets to CPU when a port is joined to Open vSwitch.
There is scope to later refine what is passed up as per Open vSwitch flows
on a port.

This does not change the behaviour of rocker ports that are
not joined to Open vSwitch.

Subject: rocker: add offload_fwd_mark support

If device flags ingress packet as "fwd offload", mark the
skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark.  This
will be the hint to the kernel that this packet has already been forwarded
by device to egress ports matching skb->offlaod_fwd_mark.

For rocker, derive port dev->offlaod_fwd_mark based on device switch ID and
port ifindex.  If port is bridged, use the bridge ifindex rather than the
port ifindex.

Refactor code to clearly separate probing non-dt versus dt. In the
non-dt case platform data must be supplied to probe successfully.
For dt the platform data structure is created and match data is
copied into it. Note that support for supplying platform data in
dt from AUXDATA is dropped as no users in mainline does this.

This change will allow dt dwmac-* drivers to call the config_dt()
function from probe to create the needed platform data struct and
retrieve common dt properties.

Export stmmac_probe_config_dt() and stmmac_get_platform_resources()
so they can be used in the dwmac-* drivers themselves. This will
allow us to build more flexible and standalone drivers which just
use stmmac_platform as a library for setup functions.

Subject: net: bcmgenet: Remove excessive PHY reset

We are currently issuing multiple PHY resets during a suspend/resume,
first during bcmgenet_power_up() which does a hardware reset, then a
software reset by calling bcmgenet_mii_reset(). This is both unnecessary
and can take as long as 10ms per MDIO transactions while we re-apply
workarounds because we do not yet have MDIO interrupts enabled.

phy_resume() takes care of re-apply our workarounds in case we need any,
and bcmgenet_power_up() does a PHY hardware reset, all of this is more
than enough to guarantee that the PHY operates correctly.

Subject: net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()

We are currently disabling the GPHY interface during bcmgenet_close(),
and attempting to power it back on during bcmgenet_open(). This works
fine for the first time, because we called bcmgenet_mii_config() which
took care of enabling the interface, however, bcmgenet_power_up() really
needs to power on the GPHY for correctness.

This will be particularly important as we want to move
bcmgenet_mii_probe() down to bcmgenet_open() to avoid seeing the "PHY
already attached" message.

Subject: net: bcmgenet: Determine PHY type before scanning MDIO bus

Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.

Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.

If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.

Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.

Subject: net: bcmgenet: Delay PHY initialization to bcmgenet_open()

We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.

This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.

Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.

Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

Subject: net: bcmgenet: Remove init parameter from bcmgenet_mii_config

Now that we have reworked the way we perform the PHY initialization, we
no longer need to differentiate between init time vs. non-init time
calls, just use a dev_info_once() print to print the PHY type.

__vxlan_find_mac invokes ether_addr_equal on the eth_addr field,
which triggers unaligned access messages, so rearrange vxlan_fdb
to avoid this in the most non-intrusive way.

Subject: mwifiex: add tx data pause support

This patch adds support to enable TX data pause feature for mwifiex.
Whenever FW TX buffers reach threshold, FW would send TX pause event
to driver. Driver in turn would block data traffic to that particular
receiver address.

Subject: mwifiex: do not increase tx_pkts_queued if receive address tx paused

If tx_pkts_queued is increased for tx paused receive address, tx process
will be triggered for this packet. But since RA list was tx paused,
there will be an infinite loop in mwifiex_wmm_process_tx waiting for the
event(tx pause, tdls cs) to cancel tx pause. This will be an dead loop,
since main_process was locked at this time, there will be no opportunity
to process event.

So do not increase tx_pkts_queued if receive address tx paused,
this will be restored RA list is unpaused.

Subject: mwifiex: process tdls channel switch event

This patch add support for tdls channel switch event process.
We block TX queues for particular RA list depending upon channel
switch state. If channel switch state is moving to base channel,
we unblock RA lists for AP. If channel switch state is moving to off
channel, we unblock TDLS peer RA lists.

Subject: mwifiex: update domain_info upon band change in start_ap

It was observed that AP beacons would not reflect correct regulatory
information upon starting AP in A band. This was because of missing
AP config band update in set_channel of start_ap. Also we configure 11D
settings info FW only for specific band. So we need to download domain
info to FW even if domain remains unchanged but band is changed.

Subject: mwifiex: support for bypass tx queue

This patch adds support for another TX queue in driver- bypass
TX queue. This queue is used for sending data/mgmt packets while
in disconnected state i.e. when port is yet not unblocked.
TDLS setup packets would also be queued in this queue.

Subject: mwifiex: advertise multichannel support to cfg80211

This patch adds support to advetise mwifiex multichannel support to
cfg80211. If module parameter drcs is enabled and FW supports multichannel
operation we advertise this support to cfg80211. As of now 2 simultaneous
channels are supported.

Subject: mwifiex: separate interface combination for multichannel and DFS

Multichannel and DFS cannot be supported at same time. So when multichannel
operation is enabled by module parameter, we enable number of channel as 2
while registering wiphy. For all other cases we advertise DFS support to
cfg80211. Patch also adds support for radar detect widths parameter.

Subject: wireless: cw1200: Remove redundant spi driver bus initialization

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

Subject: mwifiex: avoid freeing improper pointer in
 mwifiex_set_wowlan_mef_entry

mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in
case of an error.  The only caller (mwifiex_set_mef_filter) passes that
pointer as an offset into allocated memory, so any attempt to free that
will not be the actual allocated pointer.

Address this by changing mwifiex_set_wowlan_mef_entry to not do any
free, and to cause mwifiex_set_mef_filter to do the appropriate free if
the call to mwifiex_set_wowlan_mef_entry fails.

Subject: mwifiex: usb: Fix double add error when submitting rx urb

There is an error that can occur where the driver adds the same URB to USB submission list twice.
This happens since mwifiex_usb_submit_rem_rx can submit packets at same time as an rx urb complete callback.
This causes list corruption and is fixed by not setting the skb to NULL when submitting an rx packet.

Subject: ath9k: make DMA stop related messages debug-only

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.

Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.

To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

Subject: mwifiex: fix for p2p broken link

This patch fixes following issues in p2p code paths.

1) bss role, bss type and connection type was not set correctly
for p2p GO and p2p client at couple of places.
2) Driver appends a proprietary header to management frames
which will be parsed by our firmware. Later while informing
TX status to cfg80211, modified frame buffer was passed to
cfg80211_mgmt_tx_status() instead of original one.

Subject: bcma: populate bus DT subnodes as platform_device-s
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Our bus should allow defining children nodes as we may want to specify
devices attached to the bus. This is required e.g. to specify NAND or
ChipCommon cores and use bus's address and IRQ mappings.

Subject: rtlwifi: rtl8821ae: Fix an expression that is always false

In routine _rtl8821ae_set_media_status(), an incorrect mask results in a test
for AP status to always be false. Similar bugs were fixed in rtl8192cu and
rtl8192de, but this instance was missed at that time.

Subject: ath9k: fix moredata flag endianness in cabq tx

While compiling ath9k with some extra flags I've
found that:

 ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer
 ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=
 ath9k/xmit.c +2474 ## 36:    left side has type restricted __le16
 ath9k/xmit.c +2474 ## 36:    right side has type int

There's no way for frame ftype/stype to be
mistreated as the offending 'moredata' flag when
considering cab queue.

This could've however theoretically led sometimes
to increased power consumption on connected
stations as they would keep their Rx active
waiting for frames that would never come.

Subject: brcmfmac: set wiphy's addresses to provide valid MACs

Broadcom's firmware requires every BSS to use MAC address with unique
last few bits. The amount of bits may depend on a particular firmware,
it was verified to be 2 for BCM43602 one.
If this condition won't be fulfilled firmware will reject such MAC:
brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52

We don't want to simply set addr_mask as it would also disallow using
locally administrated bit. Instead let's build a list of addresses
manually enabling 0x2 bit for extra interfaces.

Subject: ath9k: export HW random number generator

We measured the FFT-based entropy in 3 ways, Shannon entropy,
collision entropy, and directly measured min-entropy. Just to
be conservative, we recommend the estimated min-Entropy to be
10 bits per 16-bit value.

Analysis was done by Jacobson,David(djacobso@qti.qualcomm.com).

Subject: iwlegacy: convert hex_dump_to_buffer() to %*ph

There is no need to use hex_dump_to_buffer() in the cases like this:

	hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);	/* len <= 16 */
	sprintf("%s\n", outbuf);

since it maybe easily converted to simple:

	sprintf("%*ph\n", len, buf);

Note: it seems in the case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

Subject: vxlan: Flow based tunneling

Allows putting a VXLAN device into a new flow-based mode in which
skbs with a ip_tunnel_info dst metadata attached will be encapsulated
according to the instructions stored in there with the VXLAN device
defaults taken into consideration.

Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is
set, the packet processing will populate a ip_tunnel_info struct for
each packet received and attach it to the skb using the new metadata
dst.  The metadata structure will contain the outer header and tunnel
header fields which have been stripped off. Layers further up in the
stack such as routing, tc or netfitler can later match on these fields
and perform forwarding. It is the responsibility of upper layers to
ensure that the flag is set if the metadata is needed. The flag limits
the additional cost of metadata collecting based on demand.

This prepares the VXLAN device to be steered by the routing and other
subsystems which allows to support encapsulation for a large number
of tunnel endpoints and tunnel ids through a single net_device which
improves the scalability.

It also allows for OVS to leverage this mode which in turn allows for
the removal of the OVS specific VXLAN code.

Because the skb is currently scrubed in vxlan_rcv(), the attachment of
the new dst metadata is postponed until after scrubing which requires
the temporary addition of a new member to vxlan_metadata. This member
is removed again in a later commit after the indirect VXLAN receive API
has been removed.

From 3093fbe7ff4bc7d1571fc217dade1cf80330a714 Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Tue, 21 Jul 2015 10:44:00 +0200
Subject: route: Per route IP tunnel metadata via lightweight tunnel

This introduces a new IP tunnel lightweight tunnel type which allows
to specify IP tunnel instructions per route. Only IPv4 is supported
at this point.

From e7030878fc8448492b6e5cecd574043f63271298 Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Tue, 21 Jul 2015 10:44:01 +0200
Subject: fib: Add fib rule match on tunnel id

This add the ability to select a routing table based on the tunnel
id which allows to maintain separate routing tables for each virtual
tunnel network.

ip rule add from all tunnel-id 100 lookup 100
ip rule add from all tunnel-id 200 lookup 200

A new static key controls the collection of metadata at tunnel level
upon demand.

From 614732eaa12dd462c0ab274700bed14f36afea5e Mon Sep 17 00:00:00 2001
From: Thomas Graf <tgraf@suug.ch>
Date: Tue, 21 Jul 2015 10:44:06 +0200
Subject: openvswitch: Use regular VXLAN net_device device

This gets rid of all OVS specific VXLAN code in the receive and
transmit path by using a VXLAN net_device to represent the vport.
Only a small shim layer remains which takes care of handling the
VXLAN specific OVS Netlink configuration.

Unexports vxlan_sock_add(), vxlan_sock_release(), vxlan_xmit_skb()
since they are no longer needed.

From d2eac98f7d1b950b762a7eca05a9ce0ea1d878d2 Mon Sep 17 00:00:00 2001
From: Florian Fainelli <f.fainelli@gmail.com>
Date: Mon, 20 Jul 2015 17:49:55 -0700
Subject: net: dsa: bcm_sf2: Do not override speed settings

The SF2 driver currently overrides speed settings for its port
configured using a fixed PHY, this is both unnecessary and incorrect,
because we keep feedback to the hardware parameters that we read from
the PHY device, which in the case of a fixed PHY cannot possibly change
speed.

This is a required change to allow the fixed PHY code to allow
registering a PHY with a link configured as DOWN by default and avoid
some sort of circular dependency where we require the link_update
callback to run to program the hardware, and we then utilize the fixed
PHY parameters to program the hardware with the same settings.

Fixes: 246d7f773c13 ("net: dsa: add Broadcom SF2 switch driver")

Subject: net: phy: fixed_phy: handle link-down case

fixed_phy_register() currently hardcodes the fixed PHY link to 1, and
expects to find a "speed" parameter to provide correct information
towards the fixed PHY consumer.

In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band
status auto-negotiation) fixed PHYs, none of these parameters can be
provided since they will be auto-negotiated, hence, we just provide a
zero-initialized fixed_phy_status to fixed_phy_register() which makes it
fail when we call fixed_phy_update_regs() since status.speed = 0 which
makes us hit the "default" label and error out.

Without this change, we would also see potentially inconsistent
speed/duplex parameters for fixed PHYs when the link is DOWN.

Subject: of_mdio: add new DT property 'managed' to specify the PHY management
 type

Currently the PHY management type is selected by the MAC driver arbitrary.
The decision is based on the presence of the "fixed-link" node and on a
will of the driver's authors.
This caused a regression recently, when mvneta driver suddenly started
to use the in-band status for auto-negotiation on fixed links.
It appears the auto-negotiation may not work when expected by the MAC driver.
Sebastien Rannou explains:
<< Yes, I confirm that my HW does not generate an in-band status. AFAIK, it's
a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with
inband status) is connected to the switch through QSGMII, and in this context
we are on the media side of the PHY. >>
https://lkml.org/lkml/2015/7/10/206

This patch introduces the new string property 'managed' that allows
the user to set the management type explicitly.
The supported values are:
"auto" - default. Uses either MDIO or nothing, depending on the presence
of the fixed-link node
"in-band-status" - use in-band status

Subject: mvneta: use inband status only when explicitly enabled

The commit 898b2970e2c9 ("mvneta: implement SGMII-based in-band link state
signaling") implemented the link parameters auto-negotiation unconditionally.
Unfortunately it appears that some HW that implements SGMII protocol,
doesn't generate the inband status, so it is not possible to auto-negotiate
anything with such HW.

This patch enables the auto-negotiation only if explicitly requested with
the 'managed' DT property.

This patch fixes the following regression:

Subject: sfc: enable cascaded multicast filters in MCFW

After creating event queue 0, check to see if the workaround is enabled,
 and enable it if necessary.  This will be called during PCI probe and
 also when coming back up after a reset.  The nic_data->workaround_26807
 will be used in the future to control the filter insertion behaviour
 based on this workaround.

Only the primary PF can enable this workaround, so tolerate an EPERM
 error and continue.  Otherwise, if any step in the checking and enabling
 of the workaround fails, the event queue must be removed.

We check that workaround is implemented before trying to enable it,
 and store the current workaround setting before trying to change it.

Subject: sfc: cope with ENOSYS from efx_mcdi_get_workarounds()

GET_WORKAROUNDS was only introduced in May 2014, not all firmware
 will have it.  So call sites need to handle ENOSYS.
In this case we're probing the bug26807 workaround, which is not
 implemented in any firmware that doesn't have GET_WORKAROUNDS.
 So interpret ENOSYS as 'false'.

Subject: sfc: warn if other functions have been reset by MCFW

When enabling the workaround for cascaded multicast filters, the MC
 can reset other functions if they have already inserted filters.
 In that case, the workaround has been enabled, but print an info
 message in the log recording that other functions had to be reset.

As other functions were reset, the MC will have incremented its boot
 count, so also increment the warm_boot_count on the function which
 enabled the workaround, as that function won't have received an MC
 reboot event and does not need to reset.

Subject: sfc: Insert multicast filters as well as mismatch filters in
 promiscuous mode

If a function is in promiscuous mode and another function has a broadcast or
 multicast filter inserted, the function in promiscuous mode won't see that
 broadcast or multicast traffic.
Most notably this breaks broadcast, which means ARP doesn't work. Less
 show-stoppingly, a function listening on a multicast address that's also in
 promiscuous mode will not see that multicast traffic if another function is
 also listening on that multicast address.

This change is only re-factoring; there are no changes to functionality
 except for a slight elaboration of an error message (on mismatch filter
 insertion failure).

Subject: sfc: support cascaded multicast filters

If the workaround to support cascaded multicast filters ("workaround_26807") is
enabled, the broadcast filter and individual multicast filters are not inserted
when in promiscuous or allmulti mode.

There is a race while inserting and removing filters when entering and leaving
promiscuous mode.  When changing promiscuous state with cascaded multicast
filters, the old multicast filters are removed before inserting the new filters
to avoid duplicating packets; this can lead to dropped packets until all
filters have been inserted.

The efx_nic:mc_promisc flag is added to record the presence of a multicast
promiscuous filter; this gives a simple way to tell if the promiscuous state is
changing.

Subject: sfc: clean fallbacks between promisc/normal in
 efx_ef10_filter_sync_rx_mode

Separate functions for inserting individual and promisc filters; explicit
 fallback logic in efx_ef10_filter_sync_rx_mode(), in order not to overload
 the 'promisc' flag as also meaning "fall back to promisc".

Subject: cxgb4: Add debugfs entry to enable backdoor access

Add debugfs entry 'use_backdoor' to enable backdoor access to read sge
context. By default, we read sge context's via firmware. In case of FW
issues, one can enable backdoor access via debugfs to dump sge context
for debugging purpose.

Subject: bnx2x: Utilize FW 7.12.30

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:

 - Packets from a VF with pvid configured which were sent with a
   different vlan were transmitted instead of being discarded.

 - FCoE traffic might not recover after a failue while there's traffic
   to another function.

In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

From 4ad79e1301f48b8c4ed2cc71c85e9b224a16b3e3 Mon Sep 17 00:00:00 2001
From: Yuval Mintz <Yuval.Mintz@qlogic.com>
Date: Wed, 22 Jul 2015 09:16:23 +0300
Subject: bnx2x: Rebrand from 'broadcom' into 'qlogic'

bnx2x still appears as a Broadcom driver even though the devices it
utilizes belong to Qlogic for more than a year.

This patch changes the various headers and the device strings to indicate
the correct ownership of the device.

From c48f350ff5e75abae2627c2531780264f9e49130 Mon Sep 17 00:00:00 2001
From: Yuval Mintz <Yuval.Mintz@qlogic.com>
Date: Wed, 22 Jul 2015 09:16:26 +0300
Subject: bnx2x: Add MFW dump support

Devices with up-to-date management FW will be able to store register dumps
on their persistent storage - in case management FW identifies a fatal
error it would gather and store such dumps, which could later be retrieved
using specific debug tools.

This patch adds the necessary part in the driver in order to make the
feature operational, as well as update users [under debug] during load
in case their device contains a dump of a previous crash.

Subject: ixgbevf: add support for reporting RSS key and hash table for X550

This patch extends the reporting of the RSS key and hash table by
adding support for X550 VFs. The difference is that X550 VFs have
their own registers for RSS key and indirection table, so there is
no need to query the PF.

The RSS key and indirection table are stored in the adapter structure
during the configuration of VFRSSRK and VFRETA which in turn can be
used in ethtool for reporting.

The logic for writing VFRETA is also changed to make sure that the
indirection table is reported correctly.

In addition this patch adds defines for the VFRETA entries and number
of VFRSSRK registers as well as some whitespace cleanups.

Subject: i40e/i40evf: Fix and refactor dynamic ITR code

This patch changes the switch statement for dynamic interrupt throttling
and adds a default case. With this patch, we check the latency setting
instead of the current ITR settings and the included refactor improves
performance.

Without this patch, the ITR setting would never change dynamically, and
there was no default.

Subject: i40e: add VF capabilities to virtual channel interface

To prepare for the changes coming up in the X722 device and future
devices, the virtual channel interface has to change slightly. The VF
driver can now report what its capable of supporting, which then informs
the PF driver when it sends the configuration information back to the
VF.

A 1.1 VF driver on a 1.0 PF driver should not send its capabilities.
Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect
or depend upon receiving the VF capabilities.

All other aspects of the API are unchanged.

Subject: i40e/i40evf: add macros for virtual channel API version and device
 capability

Now that we've rolled the virtual channel API version to 1.1, add some
macros to test what version is being used by our partner in crime. For the
VF, add some macros to determine what our device capabilities are.

Subject: i40evf: handle big resets

The most common type of reset that the VF will encounter is a PF reset
that cascades down into a VF reset for each VF. In this case, the VF
will always be assigned the same VSI and recovery is fairly simple.

However, in the case of 'bigger' resets, such as a Core or EMP reset,
when the device is reinitialized, it's probable that the VF will NOT get
the same VSI. When this happens, the VF will not be able to recover, as
it will continue to request resources for its original VSI.

Add an extra state to the admin queue state machine so that the driver
can re-request its configuration information at runtime. During reset
recovery, set this bit in the aq_required field, and fetch the (possibly
new) configuration information before attempting to bring the driver
back up. Since the driver doesn't know what kind of reset it has
encountered, this step is done even for a PF reset, but it doesn't hurt
anything - it just gets the same VSI back.

Subject: i40evf: support virtual channel API version 1.1

Store off the PF's API version, then use it to determine whether or not
to send it our capabilities. Change the version checking to allow for PF
drivers with lower API versions than our current version, so we can
still talk to PF drivers over the 1.0 API.

Subject: i40e: provide correct API version to older VF drivers

This driver fully supports VF drivers using both the 1.0 and 1.1
versions of the virtual channel API. However, VF drivers using
version 1.0 get upset if we provide them with a version other than
that, and refuse to play with us.

Correct this by checking the VFs API version at the time that we
store it off, and provide the correct version number back to the VF
so we can all get along.

From 41a1d04b9d2006fdac5cab7680cff89915610944 Mon Sep 17 00:00:00 2001
From: Jesse Brandeburg <jesse.brandeburg@intel.com>
Date: Thu, 4 Jun 2015 16:24:02 -0400
Subject: i40e: use BIT and BIT_ULL macros

Use macros for abstracting (1 << foo) to BIT(foo)
and (1ULL << foo64) to BIT_ULL(foo64) in order to match
better with kernel requirements.

NOTE: the adminq_cmd.h file was not modified on purpose because
of the dependency upon firmware for that file.

Subject: Bluetooth: hci_uart: Add basic support for Intel Lightning Peak
 devices

The Intel Lightning Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is attached via the Bluetooth line discipline.

Lightning Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.

Subject: Bluetooth: btintel: Add generic function for handling hardware errors

The handling of hardware error has support for providing a vendor
specific callback to deal with the error. Move the Intel specific
function out of the USB driver into the generic module so that it
can also be utilized by the UART driver.

Subject: net: ieee802154: Remove redundant spi driver bus initialization

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

Subject: ath10k: delay device access after cold reset

It is observed that during cold reset pcie access right
after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue. This patch is tested on QCA988X. This is
also tested on QCA99X0 which is WIP.

Subject: ath10k: update tx path to support QCA99X0

Since QCA99X0 uses fragmentation descriptor differently from
other ones on tx path, we need to handle it separately.

QCA99X0 is using 48 bits for address and 16 bits for length
out of 2 dword and each values have to be programmed by frag
desc base addr + msdu id, so that hardware can retrieve
corresponding frag data.

Subject: ath10k: add support for qca99x0 Rx descriptors

QCA99X0 chip has an extra 4 bytes in rx_msdu_start,
20 bytes in rx_msdu_end and 20 bytes in rx_ppdu_end structure
which are used in htt_rx_desc and HTT Rx ring offset setup.
This is necessary for correct Rx for QCA99X0 or Rx descriptors
will be overwritten and corrupted.

With this patch QCA988X and QCA6174 will have extra 44 bytes
padding in Rx descriptor layout which is harmless.

Subject: ath10k: fix wrong initialization of struct channel

chandef is initialized with NULL and on the very next line, we are using it to
get channel, which is not correct. Channel should be initialized after
obtaining chandef.

Found by cppcheck:

Subject: ath10k: extend struct htt_mgmt_tx_dec for qca99x0

HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
rate mgmt frame has to go out in the air. It's an optional parameter,
setting this field to zero will force firmware to choose auto rate
and send the frame out.

Those 4 byte info is missed out in the current code and 10.4 firmware
ended up reading some junk in those 4 byte and sometime malfunctioning.

Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
will not process those four byte. So, adding 4 byte at the end of
struct htt_mgmt_tx_desc will not create any impact on other chipset.

Subject: be2net: support ndo_get_phys_port_id()

Add be_get_phys_port_id() function to report physical port id. The port id
should be unique across different be2net devices in the system. We use the
chip serial number along with the physical port number for this.

Currently of_default_bus_match_table is not exported so we can only use
this feature when bcma is build into the kernel. This patch removes
support for child buses when bcma is build as a module as a temporary
fix for a build problem introduces in this commit:

Subject: hv_netvsc: Wait for sub-channels to be processed during probe

The current code returns from probe without waiting for the proper handling
of subchannels that may be requested. If the netvsc driver were to be rapidly
loaded/unloaded, we can  trigger a panic as the unload will be tearing
down state that may not have been fully setup yet. We fix this issue by making
sure that we return from the probe call only after ensuring that the
sub-channel offers in flight are properly handled.

Subject: net: bcmgenet: Remove checks on clock handles

Instead of multiplying the number of checks for IS_ERR(priv->clk),
simply NULLify the 'struct clk' pointer which is something the Linux
common clock framework perfectly deals with and does early return for
each and every single clk_* API functions.

Having every single function check for !IS_ERR(priv->clk) is both
redundant and error prone, as it turns out, we were doing it for the
main GENET clock: priv->clk, but not for the Wake-on-LAN or EEE clock,
so let's just be consistent here.

Subject: net: bcmgenet: Register link_update callback for all MoCA PHYs

Commit 8d88c6ebb34c ("net: bcmgenet: enable MoCA link state change
detection") added a fixed PHY link_update callback for MoCA PHYs when
registered using platform_data exclusively, this change is also
applicable to systems using Device Tree as their primary configuration
interface.

In order for this to work, move the link_update assignment into
bcmgenet_moca_phy_setup() where we know for sure that we are running on
a MoCA GENET instance, and do not override phydev->link since this is:

- properly taken care of by the PHY library by getting the link UP/DOWN
  interrupts
- this now runs everytime we call bcmgenet_open(), so we need to
  preserve whatever we detected before we went administratively DOWN and
  then UP
- we need to make sure that MoCA PHYs start with a link DOWN during
  probe in order to force a link transition to occur

To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
above its caller.

A timer function is itself a bottom-half, so this should be
spin_lock().

Subject: net: netcp: Fixes hw statistics module base setting error

This patch fixes error in the setting of the hw statistics
module base for K2HK platform.  In K2HK although there are
4 hw statistics modules, but only 2 are visible at a time.
Thus when setting up the pointers to the base of the
corresponding hw statistics modules, modules 0 and 2 should
point to one base, while modules 1 and 3 should point to the
other.

Subject: net: netcp: Fixes error in oversized memory allocation for statistics
 storage

The CPSW driver keeps internally some, but not all, of
the statistics available in the hw statistics modules.  Furthermore,
some of the locations in the hw statistics modules are reserved and
contain no useful information.  Prior to this patch, the driver
allocates memory of the size of the the whole hw statistics modules,
instead of the size of statistics-entries-interested-in (i.e. et_stats),
for internal storage.  This patch fixes that.

From 489e8a2f09d772afc98a85ca477bb6bc52400c26 Mon Sep 17 00:00:00 2001
From: WingMan Kwok <w-kwok2@ti.com>
Date: Thu, 23 Jul 2015 15:57:23 -0400
Subject: net: netcp: Fixes to CPSW statistics collection

In certain applications it's beneficial to allow the CPSW h/w
stats counters to continue to increment even while the kernel
polls them. This patch implements this behavior for both 1G
and 10G ethernet subsystem modules.

Subject: net/mlx5e: Support ETH_RSS_HASH_XOR

The ConnectX-4 HW implements inverted XOR8.
To make it act as XOR we re-order the HW RSS indirection table.

Set XOR to be the default RSS hash function and add ethtool API to
control it.

Subject: net/mlx5e: Allocate DMA coherent memory on reader NUMA node

By affinity hints and XPS, each mlx5e channel is assigned a CPU
core.

Channel DMA coherent memory that is written by the NIC and read
by SW (e.g CQ buffer) is allocated on the NUMA node of the CPU
core assigned for the channel.

Channel DMA coherent memory that is written by SW and read by the
NIC (e.g SQ/RQ buffer) is allocated on the NUMA node of the NIC.

Doorbell record (written by SW and read by the NIC) is an
exception since it is accessed by SW more frequently.

Subject: net/mlx5e: TX latency optimization to save DMA reads

A regular TX WQE execution involves two or more DMA reads -
one to fetch the WQE, and another one per WQE gather entry.

These DMA reads obviously increase the TX latency.
There are two mlx5 mechanisms to bypass these DMA reads:
1) Inline WQE
2) Blue Flame (BF)

An inline WQE contains a whole packet, thus saves the DMA read/s
of the regular WQE gather entry/s. Inline WQE support was already
added in the previous commit.

A BF WQE is written directly to the device I/O mapped memory, thus
enables saving the DMA read that fetches the WQE.

The BF WQE I/O write must be in cache line granularity, thus uses
the CPU write combining mechanism.
A BF WQE I/O write acts also as a TX doorbell for notifying the
device of new TX WQEs.
A BF WQE is written to the same I/O mapped address as the regular TX
doorbell, thus this address is being mapped twice - once by ioremap()
and once by io_mapping_map_wc().

While both mechanisms reduce the TX latency, they both consume more CPU
cycles than a regular WQE:
- A BF WQE must still be written to host memory, in addition to being
  written directly to the device I/O mapped memory.
- An inline WQE involves copying the SKB data into it.

To handle this tradeoff, we introduce here a heuristic algorithm that
strives to avoid using these two mechanisms in case the TX queue is
being back-pressured by the device, and limit their usage rate otherwise.

An inline WQE will always be "Blue Flamed" (written directly to the
device I/O mapped memory) while a BF WQE may not be inlined (may contain
gather entries).

Preliminary testing using netperf UDP_RR shows that the latency goes down
from 17.5us to 16.9us, while the message rate (tested with pktgen) stays
the same.

Subject: bonding: convert num_grat_arp to the new bonding option API

num_grat_arp wasn't converted to the new bonding option API, so do this
now and remove the specific sysfs store option in order to use the
standard one. num_grat_arp is the same as num_unsol_na so add it as an
alias with the same option settings. An important difference is the option
name which is matched in bond_sysfs_store_option().

Subject: dsa: mv88e6352/mv88e6xxx: Move temperature sensor code to mv88e6xxx.c

Move the temperature sensing code for mv88e6352 and mv88e6320 families
into mv88e6xxx.c to simplify adding support for additional chips.

With this change, mv88e6xxx_6320_family() no longer needs to be
a global function and is made static.

Subject: ravb: minimize TX data copying

Renesas Ethernet AVB controller requires that all data are aligned on 4-byte
boundary.  While it's  easily achievable for  the RX  data with  the help of
skb_reserve() (we even align on 128-byte boundary as recommended by the manual),
we  can't  do the same with the TX data, and it always comes  unaligned from
the networking core. Originally we solved it an easy way, copying all packet
to  a  preallocated  aligned buffer; however, it's enough to copy only up to
3 first bytes from each packet, doing the transfer using 2 TX descriptors
instead of just 1. Here's an implementation of the new  TX algorithm that
significantly reduces the driver's memory requirements.

Subject: net/mlx4_core: Preparations for 802.1ad VLAN support

mlx4_core preparation to support hardware accelerated 802.1ad VLAN
device.

To allow 802.1ad accelerated device, "packet has vlan" (phv)
Firmware capability should be available. Firmware without the
phv capability won't behave properly and can't support 802.1ad device
acceleration.

The driver checks the Firmware capability and sets the phv bit
accordingly in SET_PORT command.

Subject: net/mlx4_en: Prepare ethtool private flags to support more flags

Currently we support only one ethtool private flag. Prepare
mlx4_en_set_priv_flags function to support more than one private flag.
Will be used in the next patch to support hardware accelerated 802.1ad
vlan.

Subject: net/mlx4_en: Add support for hardware accelerated 802.1ad vlan

To enable device support in accelerated 802.1ad vlan, the port
capability "packet has vlan enable" (phv_en) should be set.
Firmware won't work properly, in case phv_en is not set.

The user can enable "phv_en" port capability with the new ethtool
private flag phv-bit. The phv-bit private flag default value is OFF,
users who are interested in 802.1ad hardware acceleration should turn ON
the phv-bit private flag:
$ ethtool --set-priv-flags eth1 phv-bit on

Once the private flag is set, the device is ready for 802.1ad vlan
acceleration.

The user should also change the interface device features and turn on
"tx-vlan-stag-hw-insert" which is off by default:
$ ethtool -K eth1  tx-vlan-stag-hw-insert on

"phv-bit" private flag setting is available only for Physical
Functions(PF), the Virtual Function (VF) will be able to use the feature
by setting "tx-vlan-stag-hw-insert" ethtool device feature only if the
feature was enabled by the Hypervisor.

Subject: stmmac: dwmac-ipq806x: turn setup callback into a probe function

By using a few functions from stmmac_platform a proper probe
function can be created from the setup glue callback. This
makes it look more like a standard driver and the OF match
data can also be dropped.

Subject: stmmac: dwmac-socfpga: turn setup callback into a probe function

By using a few functions from stmmac_platform a proper probe
function can be created from the setup glue callback. This
makes it look more like a standard driver and the OF match
data can also be dropped.

Subject: stmmac: let dwmac-* drivers handle their own match data

Since only a few of the dwmac-* drivers actually need to use
the OF match move handling into the dwmac-* drivers that need
it. This will also allow dwmac-* drivers to use their own
custom match data structure.

Subject: stmmac: dwmac-sti: use custom of match structure

Create a new private structure for OF match data in the
dwmac-sti driver. This enables us to eventually drop the
common OF match data structure which contains a lot of
unused fields.

Subject: stmmac: remove setup/free glue callbacks

As all dwmac-* drivers have been converted to have a proper probe
function the setup callback can now be removed. Also remove the
free callback that wasn't used by any driver.

New dwmac-* drivers should implement standard probe and remove
functions to preform any needed setup and teardown.

Subject: stmmac: dwmac-sti: refactor the init glue callbacks

Remove the two platform specific init callbacks and make
them use a common one by creating a function member in
the internal data structure. This allow us to remove the
layer of indirection and simplify the code a bit.

Subject: ath10k: suppress 'failed to process fft' warning messages

When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.

This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.

DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

Symptoms seen & fix tested in both debug & non-debug modes on TP-Link
Archer C7 v2 platform.

Subject: ath10k: Improve performance by reducing tx_lock contention

During tx completion, tx_lock is held for longer than required, preventing
efficient refill of htt->pending_tx. Refactor the code so that only MSDU
related operations are protected by the lock.

Improves downstream performance on a dual-core ARM Freescale LS1024A
(f.k.a. Mindspeed Comcerto 2000) AP with a 3x3 client from 495 to 580 Mbps.
Other CPU bound multicore systems may also benefit.

Subject: ath10k: enable raw encap mode and software crypto engine

This patch enables raw Rx/Tx encap mode to support software based
crypto engine. This patch introduces a new module param 'cryptmode'.

 cryptmode:

   0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
      encapsulation to the firmware. This is the default mode.
   1: Use sofware crypto engine globally with raw mode TX/RX
      encapsulation to the firmware.

Known limitation:
   A-MSDU must be disabled for RAW Tx encap mode to perform well when
   heavy traffic is applied.

Testing: (by Michal Kazior <michal.kazior@tieto.com>)

     a) Performance Testing

        killer1525  ->  qca988x     203.689 mbps [tcp1 ip4]
        killer1525  ->  qca988x     222.339 mbps [tcp5 ip4]
        killer1525  ->  qca988x     264.199 mbps [udp1 ip4]
        killer1525  ->  qca988x     479.371 mbps [udp5 ip4]

      Note:
       - only open network tested for RAW vs nwifi performance comparison
       - killer1525 (qca6174 hw2.2) is 2x2 device (hence max 866mbps)
       - used iperf
       - OTA, devices a few cm apart from each other, no shielding
       - tcpX/udpX, X - means number of threads used

      Overview:
       - relative Tx performance drop is seen but is within reasonable and
         expected threshold (A-MSDU must be disabled with RAW Tx)

     b) Connectivity Testing

Subject: net: netcp: Fixes efuse mac addr swap on k2e and k2l

On some of the K2E and K2L platforms, the two DWORDs in
efuse occupied by the pre-programmed mac address for
slave port 1 are swapped.  To workaround this issue,
this patch adds a new define NETCP_EFUSE_ADDR_SWAP (2)
which signifies the occurrence of such swapping so that
the driver can take proper action.  The flag can be
enabled in the corresponding netcp interface dts binding
as efuse-mac = <2>  under the corresponding netcp
interface node.

Subject: gianfar: Fix warnings when built on 64-bit

As part of defconfig consolidation using fragments, we'd like to be
able to have the same drivers enabled on 32-bit and 64-bit.  Gianfar
happens to only exist on 32-bit systems, and when building the
resulting 64-bit kernel warnings were produced.

A couple of the warnings are trivial, but the rfbptr code has deeper
issues.  It uses the virtual address as the DMA address, which again,
happens to work in the environments where this driver is currently
used, but is not the right thing to do.

support")

Subject: net/mlx5e: Remove the mlx5e_update_priv_params() function

It was used to update netdev priv parameters that require stopping
and re-opening the device in a generic way - it got the new
parameters and did: ndo_stop(), copy new parameters into current
parameters, ndo_open().

We chose to remove it for two reasons:
1) It requires additional instance of struct mlx5e_params on the
   stack and looking forward we expect this struct to grow.
2) Sometimes we want to do additional operations (besides
   just updating the priv parameters) while the netdev is stopped.
   For example, updating netdev->mtu @mlx5e_change_mtu() should
   be done while the netdev is stopped (done in this commit).

From 05cc5a39ddb74dd81a716a45e67b938d8ebed463 Mon Sep 17 00:00:00 2001
From: Yuval Mintz <Yuval.Mintz@qlogic.com>

Subject: bnx2x: add vlan filtering offload

Current driver always uses vlan-promisc mode, i.e., it receives both
tagged and untagged traffic and lets the network stack drop packets
tagged with unrequested vlan tags.

This patch implements vlan-filtering offload in the driver -
Unless explicitly configured to promisc mode, only untagged packets or
packets tagged with requested vlans would reach the Rx flow.

Subject: be2net: Support vxlan offload stats in the driver

This patch adds vxlan offload specific counters to ethtool stats. We
provide tx/rx queue counters to show the number of vxlan offload pkts
sent/received.

Subject: mlxsw: Introduce Mellanox switch driver core

Add core components of Mellanox switch driver infrastructure.
Core infrastructure is designed so that it can be used by multiple
bus drivers (PCI now, I2C and SGMII are planned to be implemented
in the future). Multiple switch kind drivers can be registered as well.
This core serves as a glue between buses and drivers.

Subject: mlxsw: Add interface to access registers and process events

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
the host and the device in order to configure the available device registers.
Another use case is notifications sent from the device to the host,
letting it know about certain events, such as port up / down.

Add the ability to construct EMADs with provisions to construct and
parse the registers' payloads. Implement EMAD transaction layer
which is responsible for the reliable transmission of EMADs. Also, add
an infrastructure used by the switch driver to register for particular
events generated by the device.

Subject: mlxsw: Introduce Mellanox SwitchX-2 ASIC support

Benefit from the previously introduced Mellanox Switch infrastructure and
add driver for SwitchX-2 ASIC. Note that this driver is very simple now.
It implements bare minimum for getting device to work on slow-path.
Fast-path offload functionality is going to be added soon.

Subject: Bluetooth: btusb: match generic class code in interface descriptor

btusb currently has a generic match on USB device descriptors:
        { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },

However, http://www.usb.org/developers/defined_class states:

  Base Class E0h (Wireless Controller)
  This base class is defined for devices that are Wireless controllers.
  Values not shown in the table below are reserved. These class codes are
  to be used in Interface Descriptors, with the exception of the Bluetooth
  class code which can also be used in a Device Descriptor.

Add a match on the interface descriptors accordingly.

This fixes compatibility with the RTL8723AU device shown below.
This device conforms to the USB Interface Association Descriptor
specification, which requires the device to have class ef/02/01.
The extra IAD descriptor then specifies that interfaces 0 and 1
belong to the same function/driver, which is true. Provided that
the Bluetooth device class spec accepts use of the IAD, I imagine that
technically, all btusb devices should be configured like this.

According Documentation/timers/timers-howto.txt the usually case for
setting up a hrtimer takes > ~10us. So we should use udelay in this
case so we are sure that the state change was done, before doing the
state change assert.

Subject: ath10k: fix memory alloc failure in qca99x0 during wmi svc rdy event

Host memory required for firmware is allocated while handling
wmi service ready event. Right now, wmi service ready is handled
in tasklet context and it calls dma_alloc_coherent() with atomic
flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
the platform (at least in AP platform) where it has less atomic
pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
for one card, having additional QCA99X0 card in the same platform
will require similarly amount of memory. So, it's not guaranteed that
all the platform will have enough atomic memory pool.

Fix this issue, by handling wmi service ready event in workqueue
context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
queue will not be ready at the time of handling wmi service ready.
So, it can't be used to handle wmi service ready. Also, register work
gets scheduled during insmod in existing ath10k_wq and waits for
wmi service ready to completed. Both workqueue can't be used for
this purpose. New auxiliary workqueue is added to handle wmi service
ready.

Subject: ath10k: increase max client to 512 in qca99x0

When max client was set to 512 in qca99x0, there was host memory
alloc failure during wmi service ready event handling. This issue
got resolved now, increasing max client limit from 256 to 512.

Subject: ath10k: initialize msdu ext. descriptor before use

Initial QCA99X0 support has a known issue with TCP Tx throughput.
All other path such as UDP Tx/Rx and TCP Rx meet their expectation
(> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
used on iperf.

The root cause is turned out because TSO flag is not initialized
properly so that firmware configures TSO in wrong way.
TSO flags in msdu extension descriptor is required to be reset
to indicate firmware there is no TSO is enabled, otherwise it
could act as TSO is enabled which causes huge throughput drop.

In fact, it's enough by resetting TSO flags only to prevent the
unexpected behavior, but initializing whole msdu ext. descriptor
will help to clear uncertainty of firmware could bring on as it
constantly updated.

Subject: Revert "ath9k: export HW random number generator"

This reverts commit 6301566e0b2dafa7d6779598621bca867962a0a2. Oleksij Rempel
noticed that the randomness doesn't look to be good enough and Stephan Mueller
commented:

"I would say that the discussed RNG does not seem fit for hooking it up with the
hwrandom framework."

http://lkml.kernel.org/g/3945775.m5HblJPgiO@tauon.atsec.com

So let's the revert the patch until we are sure that we can trust this random
generator.

Subject: Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet device
 driver

Repost patch of driver for LAN7800 family of USB 2.0 & USB 3.0 to Gigabit Ethernet.
- remove module param which can be configurable by standard mechanism.
- remove other module parms except msg_level per review comment.
- update to handle byte swap for statistics structure correctly.

Subject: ipv6: change ipv6_stub_impl.ipv6_dst_lookup to take net argument

This patch adds net argument to ipv6_stub_impl.ipv6_dst_lookup
for use cases where sk is not available (like mpls).
sk appears to be needed to get the namespace 'net' and is optional
otherwise. This patch series changes ipv6_stub_impl.ipv6_dst_lookup
to take net argument. sk remains optional.

All callers of ipv6_stub_impl.ipv6_dst_lookup have been modified
to pass net. I have modified them to use already available
'net' in the scope of the call. I can change them to
sock_net(sk) to avoid any unintended change in behaviour if sock
namespace is different. They dont seem to be from code inspection.

Subject: r8152: disable the capability of zero length

The UEFI driver would enable zero length, and the Linux driver doesn't
need it. Zero length let the hw complete the transfer with length 0,
when there is no received packet. It would add the load of USB host
controller and reduce the performance.

Subject: sfc: allow ethtool selftest and MC reboot to complete on an
 unprivileged function

The policy in the net driver is to attempt MCDI commands and
then handle any EPERM error codes appropriately when returned
by unprivileged functions.
The ethtool selftest contains some tests which are useful on
an unprivileged function, such as the event queue interrupt
tests, but other tests cannot be performed as the function
does not have the required permissions.

If a test returns -EPERM, act as though the test was not run
and continue.

Subject: bnx2x: Correct logic for pvid configuration.

Commit 05cc5a39ddb7 ("bnx2x: add vlan filtering offload") has introduced
an incorrect logic for checking whether pvid should be configured for
a vf, causing the hypervisor driver to send unneeded ramrods for all of
the vfs each time a pvid has changed.

Subject: virtio_net: add gro capability

Straightforward patch to add GRO processing to virtio_net.

napi_complete_done() usage allows more aggressive aggregation,
opted-in by setting /sys/class/net/xxx/gro_flush_timeout

Tested:

Setting /sys/class/net/xxx/gro_flush_timeout to 1000 nsec,
Rick Jones reported following results.

One VM of each on a pair of OpenStack compute nodes with E5-2650Lv3 CPUs
and Intel 82599ES-based NICs. So, two "before" and two "after" VMs.
The OpenStack compute nodes were running OpenStack Kilo, with VxLAN
encapsulation being used through OVS so no GRO coming-up the host
stack.  The compute nodes themselves were running a 3.14-based kernel.

Single-stream netperf, CPU utilizations and thus service demands are
based on intra-guest reported CPU.

During NIC initialization shared HW is reset and this disables the
scheduler. Some HW platforms do not activate the scheduler after it.
Consequently all HCMD sent by the driver stay at the queues which cause
to queue stuck.
Set the scheduler to work on auto active mode so it would be activated upon
change over one of the queues' write pointer.

Subject: iwlwifi: mvm: LRU-assign key offsets

The current key offset assignment algorithm always uses the lowest
unused key offset, which will potentially lead to issues when the
firmware will change to take the key material for TX from the key
table rather than from the TX command.

In order to avoid those issues (and avoid forgetting about them)
change the key offset allocation algorithm now to avoid reusing key
offsets quickly.

The new algorithm always picks as the next offset the least recently
freed offset, i.e. the offset that has been unused for the longest
amount of time. This is implemented by having a generation counter
for each key offset that is incremented every time a key is deleted,
except for the one that's deleted, which is reset to zero. Thus the
highest counter is the key that's been unused longest.

Subject: iwlwifi: dvm: move ADD_STA response handling to sync command

This driver currently has some very confusing ADD_STA response handling
that runs asynchronously in the background for all of the commands, but
is only really necessary for synchronous ones (the really asynchronous
ones can only be done for already existing stations), and for the sync
ones it actually waits for the RX handler to return a status code.

Rework this to keep the debug printing in the handler, but do the code
that's supposed to have an effect only for sync commands in the command
sending function.

Subject: iwlwifi: dvm: remove ADD_STA prints relying on station ID

This makes the logging a little less useful, but as they're mostly
synchronous commands it won't matter much. It gets rid of the
dependency on the input command, which this is the only user of.

In the mvm driver, neither the old command nor the return value
are used, so remove them.

From f7e6469fc90aa388ac5047e1ba914b31af9240ae Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 23 Jun 2015 21:58:17 +0200
Subject: iwlwifi: remove command and return value from opmode RX

With the previous patch series, no opmode continues using the
command or handler_status (i.e. the return value from the RX)
so it can be removed now.

Subject: iwlwifi: mvm: Do not sample the device time for session protection

Since the time-event is sent with the immediate flag set, there is
no need to sample the device time.

Subject: iwlwifi: pcie: add missing calls to synchronize_irq()

In a few places, we were disabling interrupts but didn't
make sure that the interrupt handler has finished running.
Add calls to synchronize_irq() to ensure we finish handling
the interrupts before we free resources or other things that
could lead to a crash if the interrupt were to be handled
later.

Subject: iwlwifi: pcie: don't warn on long MPDUs when supported

In iwlmvm firmwares, the Byte count written in the scheduler
byte count table is in DWORDs and not in bytes.
We should check that this value fits in the 12 bits and
the value can be either in bits of in DWORD or bytes
depending on the firmware. Check the value after the
translation to DWORDs is done (if needed).

Subject: iwlwifi: remove command header flags field

The 'flags' field really has been reserved in the firmware API for a
very long time, probably since 4965. As a consequence, the field is
always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense.

Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and
all the code for it.

Subject: iwlwifi: mvm: remove IWL_UCODE_TLV_API_BASIC_DWELL

All the supported firmwares support this API.
This includes removing dwell per band, as band is no longer a factor
in calculating the dwell. Only basic dwell is used and FW will calculate
the actual dwell time.

Subject: iwlwifi: mvm: add basic Time of Flight (802.11mc FTM) support

ToF is a time based method for measurement of the WiFi device
location within a WiFi environment. The driver functionality provided
by this patch is the interface for communication with FW and receiving
location related updates from the FW. The interface provided by this
patch is via debugfs.

From ab02165ccec4c78162501acedeef1a768acdb811 Mon Sep 17 00:00:00 2001
From: Aviya Erenfeld <aviya.erenfeld@intel.com>
Date: Tue, 9 Jun 2015 16:45:52 +0300
Subject: iwlwifi: add wide firmware command infrastructure for TX

As the firmware is slowly running out of command IDs and grouping of
commands is desirable anyway, the firmware is extending the command
header from 4 bytes to 8 bytes to introduce a group (in place of the
former flags field, since that's always 0 on commands and thus can
be easily used to distinguish between the two.

In order to support this most easily in the driver widen the command
command ID used in the command sending functions and encode the new
values (group and version) in the ID. That way existing code doesn't
have to be changed (since the higher bits are 0 automatically) and
newer code can easily use the new ID generation function to create a
value to use in place of just the command ID.

From 88742c9e84f73eeea4abe967d751b0e6318c2c2e Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 30 Jun 2015 15:31:22 +0200
Subject: iwlwifi: mvm: move existing UMAC commands to group 1

Existing UMAC commands already use the long header, but are sent
with group 0 and the long header inserted manually. Move them to
the group 1 to take advantage of the header building in the low-
level transport.

Existing firmware ignores the group_id field (it's reserved) and
the first firmware that really supports long command headers can
parse all commands in both group 0 (with short header) and group
1 (with long header.)

Subject: Revert "iwlwifi: mvm: move deferred d0i3 exit to resume_complete op"

This reverts commit 088070a2f6575402d3dd82e1c5a4a8e1941805f6.

When working in d0i3_on_idle mode, we explicitly go out
of d0i3 on resume (so other potential commands could
be sent).

However, D0I3_DEFER_WAKEUP is currently cleared on
resume complete (which happens only later on), causing
d0i3 exit to timeout.

Since mac80211 was modified to accept incoming frames
once drv_resume was called, we can safely revert this
patch, and handle the pending work on iwl_mvm_resume().

Subject: iwlwifi: mvm: Use the AP station for non_sta transmit

In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
use the AP station for multicast frames instead of the auxiliary
station as otherwise the frames can be sent to an absent P2P GO as
the FW does not block transmissions for the auxiliary station
since it is not associated with the station MAC context.

Note that this is not possible for unicast frames, as a TDLS
discovery response is sent without a station entry, and in this
case the P2P GO NoA should not block transmission to the peer.

Subject: iwlwifi: pcie: provide a way to stop configuration if it is forbidden

The firmware debug infrastructure allows the user to
provide a firmware that will toggle a few registers to
configure the debugging capabilities.
On certain devices, certain operations are forbidden.
Executing a forbidden operation will cause the hardware to
die in a way that only driver unload / load will bring it
back to life.
Fortunately, there is a way to know in advance if those
operations will be accepted by the device. This is where
the new PRPH_BLOCKBIT operation plays its role. If the bit
X from PRPH register Y is set, then we should prevent any
further register configuration. When that happens, drop a
line in the kernel log since this is really an error state:
the user won't have his device configured as he expected.
Add operations that will be used in the future:
INDIRECT_ASSIGN, INDIRECT_SETBIT, and INDIRECT_CLEARBIT.

Other debugging configurations (such as destination
configuration for the monitor) will take place in any case.

Subject: iwlwifi: mvm: Enable Rx Checksum hw

TCP software implementation on the host requires extensive computing
power.  Offloading even some of the TCP/IP stack to the NIC might save
a significant overhead. In order to enable this feature on our hw,
we need to configure it first. Once done, we mark this capability,
to be advertised later to the OS via ieee80211_register_hw.
The driver Rx indications for TCP Checksum is integrated within the
standard Rx status. The driver responds to those indications as follows:
If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
Otherwise, report CHECKSUM_NONE.

CQM overwrites a few thresholds in the bf command. On the other hand,
when entering D0i3 the thresholds are set to higher values on purpose,
so ignore CQM in this case.

Subject: iwlwifi: call d3_suspend/resume in d0i3 case as well

Some CSR registers have to be configured also
in case of suspend/resume with unified image
(which doesn't includes reconfiguration flow).

Reuse the existing d3_suspend/d3_resume trans ops,
while making sure some configurations are a bit
different, according to the wowlan type.

After this change, we no longer need the special
wowlan_d0i3 configurations done in iwl_pci_resume,
as they are already being done in the d3_resume op.

Subject: iwlwifi: pcie: reset write pointer on ict reset

Since the CSR_DRAM_INIT_TBL_WRITE_POINTER bit wasn't set
on ict reset, in some flows (like disable ict followed by
immediate reset ict) the driver and hardware went out
of sync (the driver cleared the ict_index, while the hw
kept it intact).

Subject: iwlwifi: mvm: move TX PN assignment for CCMP to the driver

Move the TX PN assignment (for CCMP only) to the driver. This prepares
the driver for future DSO (driver segmentation offload) where it will
split an SKB into multiple MPDUs by itself.

For TDLS, split out the CCMP TX command handling so that it won't get
a PN assigned, the firmware assigns the PN in that case.

Subject: iwlwifi: make various functions void in the file rs.c

This makes various functions in the file rs.c void due to these
functions never returning a error code to signal to their callers
if and how they have failed to complete their intended work.

Subject: iwlwifi: mvm: Add FW paging mechanism for the UMAC on PCI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is master on the bus(PCI) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. The FW can load / unload the pages on its own.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on PCI in order to allow the program
to use a larger virtual space while using less physical memory on the
device.

Our firmware scheduler used to suffer from false wake-up on 500 time units.
We had to came up with a formula to address this buggy behavior.
Now that our firmware is fixed, we can go back to our old policy.

Subject: iwlwifi: add new TLV capability flag for gscan support

Gscan is a scan feature which is supported on certain devices only,
hence the need for a TLV flag for it. For devices that support gscan
store the gscan capabilities advertised by the FW so the driver can
report it to upper layers.

Subject: iwlwifi: pcie: support frag SKBs

Allow frag SKBs in PCIe and advertise the maximum number of frags
to the opmode. As a fallback. linearize the SKB if it exceeds the
maximum number of fragments. This allows using the hardware better
(filling more TBs) and should improve performance when used by the
opmode.

Also adjust tracing to be able to deal with this.

Subject: iwlwifi: mvm: add the ability to trigger only monitor dumps

Change the FW debug trigger tlv to include a monitor only
option. Setting this option to true will cause fw dump triggers
to only collect monitor data and skip other dumps such as
SMEM, SRAM, CSR, PRPH, etc.
This option is used when accessing the different parts of the
firmware memory is not wanted and can cause unwanted behavior
like when debugging TX latency.

From 26d535aedc0e9fcf2c8bee65b33cecb58ee8e8ed Mon Sep 17 00:00:00 2001
From: Sara Sharon <sara.sharon@intel.com>
Date: Tue, 28 Apr 2015 12:56:54 +0300
Subject: iwlwifi: pcie: New RBD allocation model

As a preperation for multiple RX queues change the RBD
allocation model.

The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.

The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.

Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.

New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.

+ *   empty list and the driver tries to claim the pre-allocated buffers and
+ *   add them to iwl->rxq->rx_free. If it fails - it continues to claim them

+ * + In order to make sure the allocator always has RBDs to use for allocation

Subject: iwlwifi: mvm: Add FW paging mechanism for the UMAC on SDIO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Family 8000 products has 2 embedded processors, the first
known as LMAC (lower MAC) and implements the functionality from
previous products, the second one is known as UMAC (upper MAC)
and is used mainly for driver offloads as well as new features.
The UMAC is typically “less” real-time than the LMAC and is used
for higher level controls.
The UMAC's code/data size is estimated to be in the mega-byte arena,
taking into account the code it needs to replace in the driver and
the set of new features.

In order to allow the UMAC to execute code that is bigger than its code
memory, we allow the UMAC embedded processor to page out code pages on
DRAM.

When the device is slave on the bus(SDIO) the driver saves the UMAC's
image pages in blocks of 32K in the DRAM and sends the layout of the
pages to the FW. When the FW wants load / unload pages, it creates an
interrupt,	and the driver uploads / downloads the page to an address in
the a specific address on the device's memory.

The driver can support up to 1 MB of pages.

Add paging mechanism for the UMAC on SDIO in order to allow the program to
use a larger virtual space while using less physical memory on the device
itself.

Subject: iwlwifi: mvm: set different pm_timeout for action frames

When building a Tx Command for management frames, we are lacking
a check for action frames, for which we should set a different
pm_timeout.  This cause the fw to stay awake for 100TU after each
such frame is transmitted, resulting an excessive power consumption.

Subject: i40e/i40evf: RSS changes for X722

X722 uses the admin queue to configure RSS. This patch adds the necessary
flow changes to configure RSS through AQ. It also adds the separate VMDQ2
lookup tables and hash key programming for X722.

X722 also exposes a different set of PCTYPES for RSS, this patch
accommodates those changes.

Subject: i40e/i40evf: Add support for writeback on ITR feature for X722

X722 fixes an issue from X710 where TX descriptor WB would not happen if
the interrupts were disabled. In order for the write backs to happen a
bit needs to be set in the dynamic interrupt control register called
WB_ON_ITR. With this feature, the SW driver need not arm SW interrupts to
work around the issue in X710.

Subject: i40e/i40evf: Add TX/RX outer UDP checksum support for X722

X722 supports offloading of outer UDP TX and RX checksum for tunneled
packets. This patch exposes the support and leaves it enabled by
default.

Subject: i40e: Add IWARP support for X722

X722 supports IWARP, this patch handles checking for PE critical errors.
Since the driver doesn't support the IWARP interface for now, this patch
just does bare minimum to log a message oif a PE critical error
happens.

Subject: e1000e: Fix EEE in Sx implementation

This patch implements the EEE in Sx code so that it only applies to parts
that support EEE in Sx (as opposed to all parts that support EEE).
It also uses the existing eee_advert and eee_lp_abiliity to set just the
bits (100/1000) that should be set.

Subject: e1000e: Fix incorrect ASPM locking

This patch fixes wrong locking usage.
In the context of slot reset, we should use lock.
And during resume, there is no need of lock.

Subject: e1000e: Fix tight loop implementation of systime read algorithm

Change the algorithm. Read systimel twice and check for overflow.
If there was no overflow, use the first value.
If there was an overflow, read systimeh again and use the second
systimel value.

Subject: wil6210: support boot loader struct v0 & v1

There are 2 versions of boot loader struct: v0 and v1.
In the v1, boot loader build version added; as well as
RF status.

Support both versions.

Boot loader structure v1 has RF status; ignore RF error if firmware
not going to be loaded; driver can still be used to interact with the HW

Subject: wil6210: print "ulong" fields in hex format in the debugfs

In the debugfs, there is "ulong" attribute printing.
It is used for bitmap printing, and more appropriate format
would be hexadecimal, not decimal.

Subject: wil6210: wait for del_station to complete

Multiple del_station requests may be sent to the driver by the
supplicant when turning down AP. This may overflow mailbox
between the FW and ucode

Wait till disconnect of one STA completed before sending next command.

Subject: wil6210: TSO implementation

Driver report supported TSO (v4 & v6) and IP checksum offload
in addition to previously supported features. In data path
skbs are checked for non-zero gso_size, and when detected sent
to additional function for processing TSO SKBs. Since HW does not
fully support TSO, additional effort is required from the driver.
Driver partitions the data into mss sized descriptors which are
then DMAed to the HW.

Subject: wil6210: unify wmi_set_ie() error handling

When printing error message, provide string describing IE kind.
Derive it from IE type
This allows removing of error messages printing
in callers

Subject: wil6210: detailed statistics for Rx reorder drop

Rx drops may be for 2 reasons: frame is old,
or it is duplicate. On the debugfs "stations" entry,
provide counters per reorder buffer for total
frames processed, drops for these 2 reasons.
Also add debug print for dropped frames.

Subject: wil6210: remove 3-MSI support

In the recent kernel versions, multiple MSI is not well supported.
In particular, it is not supported on x86 and ARM architectures.
Also, internal interrupt handling logic is simpler and
more effective when using single interrupt.

Remove support for 3 MSI, convert module parameter
"use_msi" from int with range [0,1,3] to boolean.

Subject: wil6210: use inline functions for register access

Replace macros like "R", "W", "S", "C", defined multiple times,
with inline functions "wil_[rwsc]".

Use "readl" and "writel" instead of "ioread32" and "iowrite32"
since it is granted that memory transactions are used,
not port ones like IN/OUT

Subject: wil6210: allow to handle Rx on 2 cores

Allow network stack part of Rx processing to run on separate core,
relaxing CPU utilization on the core used for Rx NAPI.

If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
to enable RPS. The core for processing the rx skb is determined by RPS
mechanism according to rx_cpus bit mask which is configured at user level.
For processing skbs on different core from the core which processes
the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.

Subject: wil6210: system power management

Support for the system suspend/resume.
In preparation for the run-time PM, implementation made
run-time PM friendly: common for system and run-time PM
code factored out as generic functions, albeit is_runtime
parameter value is always false currently.

For debug purposes, "PM" debug category introduced.

Policy: AP-like interface can't be suspended; otherwise
suspend is allowed. Hardware brought down if interface
was up. Connection, if existed, get lost.
Interface will be brought up upon resume if it was up
before suspend.

Subject: wil6210: report boot loader error

Boot loader reports error starting from the struct v2.

Print error info before reset (power up state) in debug mode,
and print same info as error if target reset timed out.

Subject: mwifiex: sdio: reset adapter using mmc_hw_reset

Since 1fb654fd97ff("mmc: sdio: add reset callback to bus operations"),
sdio cards can be power cycled using mmc_hw_reset.
The use mmc_remove_host/mmc_add_host is discouraged, because these are
internal functions to the mmc core and should only be used by mmc hosts

Subject: mwifiex: remove redundant reset of cmd_wait_q status

mwifiex_cancel_pending_ioctl is called only from
mwifiex_cmd_timeout_func. There the wait_q status is set to
-ETIMEDWAIT before calling this function. Whether we reset the status
to -1 or leave it at -ETIMEDWAIT at end doesn't matter since both
are != 0 hence mean failure

Subject: mwifiex: remove CMD_F_CANCELED flag

CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
case it already started or starts processing the cmd.
But this was probably not working the way intended:
- it is racy: mwifiex_process_cmdresp might already have passed that
  test and is continuing to use the cmd node being recycled
- mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
  we just set to NULL
- mwifiex_recycle_cmd_node will clear the flag

The reason why it probably works is that mwifiex_cancel_pending_ioctl
is only called from mwifiex_cmd_timeout_func, where the there is little
chance of a command response still arriving

Subject: mwifiex: simplify mwifiex_complete_cmd

600f5d909a54("mwifiex: cleanup ioctl wait queue and abstraction layer")
introduced the wakeup_interruptible suppression in mwifiex_complete_cmd
b1a47aa5e1e1("mwifiex: fix system hang issue in cmd timeout error case")
then added wakup_interruptible to mwifiex_cmd_timeout_func the single
place setting a status of ETIMEDOUT.
Instead of doing extra work, using the standard call-chain will have the
same effect:
mwifiex_cancel_pending_ioctl
-> mwifiex_recycle_cmd_node
-> mwifiex_insert_cmd_to_free_q
-> mwifiex_complete_cmd
-> wake_up_interruptible

The difference is that previously the condition was not set to true,
but that's probably just an oversight in b1a47aa5e1e1 and shouldn't
have any consequence

Subject: mwifiex: using right aid value for tdls action frame

Variable pos is u8 here, so memcpy is needed to store u16 aid.
At the same time, aid should be platform independent, upper layer
utility(wpa_supplicant,etc.,) parse it as le16, so keep it le16
here.

Subject: mwifiex: fix command timeout for PCIe chipsets

When WLAN interface is up and running, driver unload and
load was causing command timeout error.

We enable Rx data by updating RX ring read pointer in
init_fw_port(). It should be done when FW is completely
intialialised. Command timeout is fixed in this patch by
moving init_fw_port() call to mwifiex_init_fw_complete().

Subject: mwifiex: fix system crash observed during initialisation

System crash was observed if one of the driver initialisation
commands is timed out. The reason is our timeout handler triggers
firmware dump, meanwhile driver initialisation error paths have
already freed the adapter structure.

Firmware hasn't yet completely initialized. So collecting firmware
dump is not needed in this case. Command timeout handler is
modified in this patch to fix the crash issue.

Subject: bnx2x: Add BD support for storage

Commit 230d00eb4bfe ("bnx2x: new Multi-function mode - BD") adds support
for the new mode in bnx2x. This expands this support by implementing
APIs required by our storage drivers to support that mode.

Subject: drivers: net: cpsw: remove disable_irq/enable_irq as irq can be
 masked from cpsw itself

CPSW interrupts can be disabled by masking CPSW interrupts and
clearing interrupt by writing appropriate EOI. So removing all
disable_irq/enable_irq as discussed in [1]

Subject: drivers: net: cpsw: dual_emac: simplify napi usage

Since interrupt is shared between the two ethernet interface and
in isr only one napi is scheduled at an instance so having two
napis doesn't make any difference. So making napi also as a
common resource for the dual ethernet interfaces.

Instead of processing tx events in isr adding separate napi for
tx which improves performance by ~180Mbps with
omap2plus_defconfig on DRA74x platform. Also cleaning up rx napis
by renaming to napi_rx for better understanding the code.

Subject: net/mlx5e: Unify the RX flow

Generally an RX packet flows through the following objects:
Flow table --> TIR --> RQT --> RQ

Where:
- TIR stands for "Transport Interface Receive", defining the RSS and
  LRO paramaters.
- RQT stands for "RQ Table", implementing the RSS indirection table.
- RQ stands for "Receive Queue"

For flows that do not need LRO, nor RSS, the driver made a shortcut to
the above RX flow by pointing to the RQ directly from the TIR, yielding
this flow:
Flow table --> TIR --> RQ

In this commit we remove this shortcut by "inserting" a single-RQ RQT
between the TIR and the RQ, i.e RX packets will reach the same RQ but
will go through an RQT of size 1, pointing to just a single RQ.

This way the RX traffic re-direction to/from the "Drop RQ" will be more
uniform (AKA "one flow"), as it will involve only RQTs re-direction and
no TIRs re-direction.

Subject: net/mlx5e: Introduce the "Drop RQ"

RX traffic routed to this RQ will be silently dropped, at the NIC HW
level.

This is in preparation for netdev "light-weight" open/stop flow
change described in previous commit.

Subject: net/mlx5e: Light-weight netdev open/stop

Create/destroy TIRs, TISs and flow tables upon PCI probe/remove rather
than upon the netdev ndo_open/stop.

Upon ndo_stop(), redirect all RX traffic to the (lately introduced)
"Drop RQ" and then close only the RX/TX rings, leaving the TIRs,
TISs and flow tables alive.

From 40ab6a6ebeebbcfc313233f5aa0d55930734f529 Mon Sep 17 00:00:00 2001
From: Achiad Shochat <achiad@mellanox.com>
Date: Tue, 4 Aug 2015 14:05:44 +0300
Subject: net/mlx5e: Rename/move functions following the ndo_stop flow change

Rename some functions that used to be invoked upon ndo_open/stop and
are now invoked upon create/destroy_netdev() in order to better hint
their place in the flow.

Change some functions location in the file so that functions involved
in ndo_open/stop flow will not be interleaved with other functions.

This is a cosmetic change, no logical change here.

Subject: net/mlx5e: Take advantage of the light-weight netdev open/stop

Now that TIRs, TISs and flow tables are kept alive while the netdev is
stopped (after executing ndo_stop()) we can do the following
improvements:

- Obsolete the active_vlans SW shadow.
- Do not delete/add flow table rules upon ndo_stop/open.
  In addition to simplifying the flow, this change also fastens
  the ndo_open/close operations.
- Obsolete synchronization of threads accessing the flow tables
  with the netdev stop/open threads.

Subject: vxlan: combine VXLAN_FLOWBASED into VXLAN_COLLECT_METADATA

IFLA_VXLAN_FLOWBASED is useless without IFLA_VXLAN_COLLECT_METADATA,
so combine them into single IFLA_VXLAN_COLLECT_METADATA flag.
'flowbased' doesn't convey real meaning of the vxlan tunnel mode.
This mode can be used by routing, tc+bpf and ovs.
Only ovs is strictly flow based, so 'collect metadata' is a better
name for this tunnel mode.

Subject: net: switchdev: change fdb addr for a byte array

The address in the switchdev_obj_fdb structure is currently represented
as a pointer. Replacing it for a 6-byte array allows switchdev to carry
addresses directly read from hardware registers, not stored by the
switch chip driver (as in Rocker).

Subject: net: dsa: mv88e6xxx: extend fid mask

The driver currently manages one FID per port (or bridge group), with a
mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
FID 0 means that multiple address databases are not being used).

This patch changes the fid_mask for an fid_bitmap of 4096 bits.

>From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
bridge groups (a bridge group gets the FID of its first member). The
remaining bits will be reserved for VLAN entries.

Subject: net: dsa: mv88e6xxx: rename ATU MAC accessors

Rename the __mv88e6xxx_{read,write}_addr functions to more explicit
_mv88e6xxx_atu_mac_{read,write} functions, which also respect the single
underscore convention used in the file (meaning SMI lock must be held).

In the meantime, define their MAC address parameters as an array of
ETH_ALEN bytes instead of a char pointer.

Subject: net: dsa: mv88e6xxx: rework FDB getnext operation

This commit adds a low level _mv88e6xxx_atu_getnext function and helpers
to rewrite the mv88e6xxx_port_fdb_getnext operation.

A mv88e6xxx_atu_entry structure is added for convenient access to the
hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value.

The previous implementation did not handle the eventual trunk mapping.
If the related bit is set, then the ATU data register would contain the
trunk ID, and not the port vector.

Check this in the FDB getnext operation and do not handle it (yet).

Subject: mlxsw: Make system port to local port mapping explicit

System ports are unique identifiers in a multi-ASIC environment that
represent all the available ports in the system. Local ports on the
other hand, are unique only within the local ASIC.

Since system port to local port mapping is not part of the HW-SW
contract and since only single-ASIC configurations are currently
supported, set an explicit 1:1 mapping by configuring the Switch System
Port Record (SSPR) register.

Subject: mlxsw: Simplify mlxsw_sx_port_xmit function

Previously we only checked if the transmission queue is not full in the
middle of the xmit function. This lead to complex logic due to the fact
that sometimes we need to reallocate the headroom for our Tx header.

Allow the switch driver to know if the transmission queue is not full
before sending the packet and remove this complex logic.

We will not release sdio bus until firmware is completely

separate firmware images for WLAN and bluetooth. This

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

This patch changes the state change behaviour of at86rf230 to always
TX_ARET mode. According the at86rf2xx datasheets TX_ARET mode doesn't
mean to be always waiting for ack frames after transmit. The transceiver
will automatically wait for ack frames or not if the acknowledge request
bit is set. See section "TX_ARET_ON – Transmit with Automatic Frame
Retransmission and CSMA-CA Retry".

Subject: mwifiex: correct TDLS link delete failure message priority

Commit d8d2f19feb16 ("mwifiex: silence TDLS link delete failure
for nonexistent link") lowers the priority of error message when
TDLS link is already deleted. But it had got increased by
commit acebe8c10a6e ("mwifiex: change dbg print func to
mwifiex_dbg")

Subject: wl18xx: use long intervals in sched scan

Add support for long intervals on sched scan.

If configured, the original request interval will
be used num_short_interval times, and then the
long interval will be used.

While on it, fix the scan command field names
to reflect the expected value is in ms (rather
than secs).

These values will be taken from the conf file,
so bump its version accordingly.

Subject: wlcore: add p2p device support

When starting a p2p mgmt interface, enable its device role. This
allows us to keep the sta role disabled and scan on the dev role.

In general, p2p management interfaces cannot send vif-specific commands
to FW, as the vif role id is invalid. Only off-channel data and scans
happen on this vif, so most ops are not relevant.

If the vif is a p2p mgmt vif, block some mac80211 ops.

Configure rate policies for p2p mgmt interface, as
otherwise p2p packets come out with arbitrary rates.

Since wpa_supplicant currently doesn't support standalone
p2p device mode (without another attached managed interface),
add p2p device to the allowed interface combinations without
decreasing the allowed station count.

Moreover, increase the station count in some cases, as AP
mode usually starts as station interface, and the AP interface
is now different from the p2p management one).

Subject: mt7601u: fix dma from stack address

DMA to variables located on the stack is a bad idea.
For simplicity and to avoid frequent allocations create
a buffer inside the device structure.  Protect this
buffer with vendor_req_mutex.  Don't protect vendor
requests which don't use this buffer.

Subject: mt7601u: fix tx status reporting contexts

mac80211 requires that rx path does not run concurrently with
tx status reporting.  Since rx path is run in driver tasklet,
tx status cannot be reported directly from interrupt context
(there would be no way to lock it out).

Add tasklet for tx and move all possible code from irq handler
there.

Note: tx tasklet is needed because workqueue is queued very
      rarely and that kills TCP performance.

Subject: bcma: fix access to host_pdev for PCIe devices

bus->host_pdev is part of a union so bus->host_pdev != NULL is probably
also true for PCIe devices, because there it accesses bus->host_pci. If
we access the dev member at the offset defined in struct
platform_device in struct pci_dev instead we probably get something
else.

This patch adds a new function which returns the host dev struct and
NULL if we do not have a host dev. When this gets registered on MIPS
brcm47xx we do not have a host dev in some situations.
This function could also be used in other places.

This problem was introduced in this commit:

Subject: net: fec: fix the race between xmit and bdp reclaiming path

When we transmit a fragmented skb, we may run into a race like the
following scenario (assume txq->cur_tx is next to txq->dirty_tx):
           cpu 0                                          cpu 1
  fec_enet_txq_submit_skb
    reserve a bdp for the first fragment
    fec_enet_txq_submit_frag_skb
       update the bdp for the other fragment
       update txq->cur_tx
                                                   fec_enet_tx_queue
                                                     bdp = fec_enet_get_nextdesc(txq->dirty_tx, fep, queue_id);
                                                     This bdp is the bdp reserved for the first segment. Given
                                                     that this bdp BD_ENET_TX_READY bit is not set and txq->cur_tx
                                                     is already pointed to a bdp beyond this one. We think this is a
                                                     completed bdp and try to reclaim it.
    update the bdp for the first segment
    update txq->cur_tx

So we shouldn't update the txq->cur_tx until all the update to the
bdps used for fragments are performed. Also add the corresponding
memory barrier to guarantee that the update to the bdps, dirty_tx and
cur_tx performed in the proper order.

Subject: net: phy: select copper mode when Marvel 88e1111 in SGMII

For the Marvel 88e1111 PHY only two SGMII modes are available, both
allowing only SGMII to copper mode (with or without clock). SGMII
to fiber mode is not supported. Make sure the fiber/copper registers
selector bits are cleared for selecting copper mode.

Subject: qlcnic: Add support to enable capability to extend minidump for iSCSI

In some cases it is required to capture minidump for iSCSI functions
as part of default minidump collection process. To enable this, firmware
exports it's capability and driver need to enable that capability
by issuing a mailbox command.

With this feature, firmware can provide additional iSCSI function's
minidump with smaller minidump capture mask (0x1f).

Subject: qlcnic: Don't use kzalloc unncecessarily for allocating large chunk
 of memory

Driver allocates a large chunk of temporary buffer using kzalloc
to copy FW image. As there is no real need of this memory to be
physically contiguous, use vzalloc instead.

Subject: Bluetooth: hciuart: Add support QCA chipset for UART

QCA61x4 chips have supported sleep feature using In-Band-Sleep commands
to enable sleep feature based on H4 protocol. After sending
patch/nvm configuration is done, IBS mode will be up and running

Subject: net, thunder, bgx: Add support to get MAC address from ACPI.

Currently there is no way to get the MAC address in a firmware
independent manner, so set the MAC address of the device directly from
the ACPI tables.

The binding agrees with the proposed standard here:

http://www.uefi.org/sites/default/files/resources/nic-request-v2.pdf

Based on code from: Narinder Dhillon <ndhillon@cavium.com>

Date: Mon, 10 Aug 2015 09:09:47 -0400
Subject: net: dsa: mv88e6xxx: extend fid mask

The driver currently manages one FID per port (or bridge group), with a
mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
FID 0 means that multiple address databases are not being used).

This patch changes the fid_mask for an fid_bitmap of 4096 bits.

>From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
bridge groups (a bridge group gets the FID of its first member). The
remaining bits will be reserved for VLAN entries.

Subject: net: dsa: mv88e6xxx: rename ATU MAC accessors

Rename the __mv88e6xxx_{read,write}_addr functions to more explicit
_mv88e6xxx_atu_mac_{read,write} functions, which also respect the single
underscore convention used in the file (meaning SMI lock must be held).

Subject: net: dsa: change FDB routines prototypes

Change the prototype of port_getnext to include a vid parameter.

This is necessary to introduce the support for VLAN.

Also rename the fdb_{add,del,getnext} function pointers to
port_fdb_{add,del,getnext} since they are specific to a given port.

Subject: net: dsa: mv88e6xxx: rework FDB add/del operations

Add a mv88e6xxx_atu_entry structure and a low level function for the ATU
Load operation, and provide FDB add and delete wrappers functions.

This implementation handles the eventual trunk mapping. If the related
bit is set, then the ATU data register would contain the trunk ID, and
not the port vector.

Subject: net: dsa: mv88e6xxx: rework FDB Get Next operation

Add a low level _mv88e6xxx_atu_getnext function for convenient access to
the hardware, and rework the FDB Get Next operation.

This will ease the future integration with VLAN IDs.

Subject: Bluetooth: hci_bcm: Add PM for BCM devices

Retrieve "shutdown" and "device_wakeup" GPIOs from ACPI.
Set device off during platform device enumeration.
Set device on only when attached.
As driver can be unbound we need to check if the bcm_device still exists
before calling GPIO's functions, this is protected using device_list_lock.

Subject: Bluetooth: hci_bcm: Retrieve UART speed from ACPI

Parse platform_device's ACPI to retrieve UART init speed.
When BCM device is open, check if its TTY has same parent as one of the
platform devices saved. If yes, use platform_device's init speed.

Subject: Bluetooth: hci_bcm: improve use of gpios API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

devm_gpiod_get currently has an optional parameter to set initial
direction and value for the requested gpio. Make use of this to simplify
the driver and make it not fail to build when this parameter is made
mandatory (which is scheduled for 4.3-rc1).

Moreover use the _optional variant of devm_gpiod_get to simplify error
handling (which also gets more strict for free).

Subject: hv_netvsc: Set vRSS with num_chn in RNDIS filter

Uses device_info->num_chn to pass user provided number of vRSS
queues (from ethtool --set-channels) to rndis_filter_device_add. If
nonzero and less than the maximum, set net_device->num_chn to the given
value; else default to prior algorithm.

Always initialize struct device_info to 0, otherwise not all its fields
are guaranteed to be 0, which is necessary when checking if num_chn has
been purposefully set.

This enables the use of ethtool --set-channels devname combined N to
change the number of vRSS queues. Separate rx, tx, and other parameters
are not supported. The maximum is rsscap.num_recv_que. It passes the
given value to rndis_filter_device_add through the device_info->num_chn

If the procedure fails, it attempts to recover to the prior state. If
the recovery fails, it logs an error and aborts.

Current num_chn is saved and restored when changing the MTU.

Subject: net: atl1c: add BQL support

This BQL implementation is mostly derived from its related driver, alx.
Tested on AR8131 (rev c0) [1969:1063]. Saturated a 100mbps link with 5
concurrent runs of netperf. Ping latency dropped from 14ms to 3ms.

Subject: net: fec: Remove unneeded use of IS_ERR_VALUE() macro

There is no need to use the IS_ERR_VALUE() macro for checking
the return value from pm_runtime_* functions.

Just do a simple negative test instead.

The semantic patch that makes this change is available
in scripts/coccinelle/api/pm_runtime.cocci.

Subject: iwlwifi: mvm: don't set K1/K2 for AES-CMAC

According to firmware engineers, the firmware has never required
these fields and the values have always been calculated, they were
just leftovers from a previous implementation.

Therefore remove the unnecessary calculation.

Subject: ath10k: reject 11b tx fragmentation configuration

Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble
frames.

Hence implement a dummy callback just to say
fragmentation isn't supported. This effectively
prevents mac80211 from doing frame fragmentation
in software.

This fixes Tx becoming broken after setting
fragmentation threshold.

Subject: ath10k: Support different txbf configuration schemes

qca61x4 uses the vdev param as a sole sufficient configuration
for txbf while qca99x0 enables txbf during peer assoc by
combining the vdev param value with peer assoc's vht capabilities

This patch gets the appropriate txbf configuration scheme
before passing the wmi command to enable the same in the firmware.

Subject: ath10k: don't remove peer that doesn't exist

If peer creation failed during offchannel Tx the
driver attempted to delete the peer nonetheless.
This caused the ar->num_peers counter to be
incorrectly decremented. This subsequently could
cause the counter to drop below 0 and also
eventually lead to firmware crash because host
would think there are less peer entries created in
firmware then there really were.

Subject: ath9k_htc: match wait_for_completion_timeout return type

Return type of wait_for_completion_timeout is unsigned long not int.
As time_left is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.

API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/ath9k/htc_hst.c:171
	int return assigned to unsigned long
./drivers/net/wireless/ath/ath9k/htc_hst.c:277
	int return assigned to unsigned long
./drivers/net/wireless/ath/ath9k/htc_hst.c:206
	int return assigned to unsigned long

Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_ATH9K_HTC=m

Patch is against 4.1-rc3 (localversion-next is -next-20150514)

Subject: ath9k_htc: drv_init: match wait_for_completion_timeout return type

Return type of wait_for_completion_timeout is unsigned long not int.
As time_left is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.

API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/ath9k/htc_drv_init.c:81
	int return assigned to unsigned long

Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_ATH9K_HTC=m

Patch is against 4.1-rc3 (localversion-next is -next-20150514)

Subject: rtlwifi: rtl8192ce: rtl8192cu: Fix endian issue

Commit e996db69833a (rtlwifi: rtl8192c: Add init codes for "fw_version"
and "fw_subversion") added initialization for fw_version, but failed to
note that the variable in the firmware header is little-endian. The
following Sparse warning results:

  CHECK   drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36: warning: incorrect type in assignment (different base types)
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    expected unsigned short [unsigned] [usertype] fw_version
drivers/net/wireless/rtlwifi/rtl8192c/fw_common.c:242:36:    got restricted __le16 [usertype] version

When fixing this problem, I noticed that several of the drivers contain
nearly identical copies of the firmware header struct, and that only the one
used in rtl8192c{e,u} had correct endian notation. The struct has been
moved into a common header, and the other drivers will be fixed in
subsequant patches.

Subject: rtlwifi: rtl8192de: Fix firmware header endian issues

This driver is converted to use the common firmware header struct.
Because the old header definition failed to indicate that the multi-byte
entries should be little endian, several problems were thus exposed.
These are fixed.

Subject: rtlwifi: rtl8192c-common: Fix two typos

In this driver, two variables are masked by one quantity, and then tested
against a second number with more bits that the mask. Accordingly, the
test always fails. To minimize the possibility of such typos, a symbolic
definition of the mask is created and used.

The separate load and mask operations are also combined into a single
statement.

Subject: mwifiex: add firmware dump support for SD8997

This patch adds firmware dump feature for SD8997 chipset.
The difference here is only one memory type is needed
to save all firmware information. Device dump information
will be uploaded to usersapace file.

Subject: mwifiex: claim sdio bus while downloading the firmware

Our 8887 A2 chip can have separate firmware images for
bluetooth and WLAN. We observed an issue during parallel
downloading of these images by btmrvl and mwifiex drivers.

This patch claims sdio bus before starting of the firmware
download in mwifiex and releases it after completion to
fix the problem.

Subject: orinoco: Do not call wiphy_unregister() from free_orinocodev()

alloc_orinocodev() would allocate the wiphy entry, but it would only get
registered much later in orinoco_init(). If something failed in the init
process inbetween the call to alloc_orinocodev() and the completion
of orinoco_init(), the drivers would end up calling wiphy_unregister()
with a NULL pointer causing beautiful OOPS fireworks.

Explicitly call wiphy_unregister() instead in the right places.

Subject: drivers: net: cpsw: add am335x errata workarround for interrutps

As per Am335x Errata [1] Advisory 1.0.9, The CPSW C0_TX_PEND and
C0_RX_PEND interrupt outputs provide a single transmit interrupt
that combines transmit channel interrupts TXPEND[7:0] and a
single receive interrupt that combines receive channel interrupts
RXPEND[7:0]. The TXPEND[0] and RXPEND[0] interrupt outputs are
connected to the ARM Cortex-A8 interrupt controller (INTC) rather
than the C0_TX_PEND and C0_RX_PEND interrupt outputs. So even
though CPSW interrupt is cleared by writing appropriate values to
EOI register the interrupt is not cleared in IRQ controller. So
interrupt is still pending and CPU is struck in ISR, the
workaround is to disable the interrupts in ARM irq controller.

Subject: Add a matching set of device_ functions for determining mac/phy

OF has some helper functions for parsing MAC and PHY settings.
In cases where the platform is providing this information rather
than the device itself, there needs to be similar functions for ACPI.

These functions are slightly modified versions of the ones in
of_net which can use information provided via DT or ACPI.

Subject: Convert smsc911x to use ACPI as well as DT

Add ACPI bindings for the smsc911x driver. Convert the DT specific calls
to nonspecific device* calls, This allows the driver to work
with both ACPI and DT configurations. Ethernet should now work when using
ACPI on ARM Juno.

no event when the neigh is removed from the device (such as when the device
goes admin down).  This patches hooks ndo_neigh_destroy so the driver can
know when a neigh is removed from the device.  In response, the driver will
purge the neigh entry from its internal tbl.

I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
this ndo is vestigial or if there are out-of-tree users.  In any case, it
does what I need here.  An alternative design would be to generate
NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to
NUD_NONE so driver knows neigh entry is dead.

Subject: net: dsa: mv88e6xxx: add VLAN Get Next support

Implement the port_pvid_get and vlan_getnext driver functions required
to dump VLAN entries from the hardware, with the VTU Get Next operation.

Some functions and structure will be shared with STU operations, since
their table format are similar (e.g. STU data entries are accessible
with the same registers as VTU entries, except with an offset of 2).

forwarding database assigned to a given VLAN port.

Finally update the FDB getnext operation to iterate on the next valid
port VLAN when the end of the current database is reached.

Subject: net: dsa: mv88e6xxx: add VLAN Purge support

Add support for the VTU Load Purge operation and implement the
port_vlan_del driver function to remove a port from a VLAN entry, and
delete the VLAN if the given port was its last member.

Subject: net: dsa: mv88e6xxx: add VLAN Load support

Implement port_pvid_set and port_vlan_add to add new entries in the VLAN
hardware table, and join ports to them.

The patch also implement the STU Get Next and Load Purge operations,
since it is required to have a valid STU entry for at least all VLANs.

Each VLAN has its own forwarding database, with FID num_ports+1 to 4095.

Subject: net: dsa: mv88e6xxx: use port 802.1Q mode Secure

This commit changes the 802.1Q mode of each port from Disabled to
Secure. This enables the VLAN support, by checking the VTU entries on
ingress.

Subject: net: Introduce VRF device driver

This driver borrows heavily from IPvlan and teaming drivers.

Routing domains (VRF-lite) are created by instantiating a VRF master
device with an associated table and enslaving all routed interfaces that
participate in the domain. As part of the enslavement, all connected
routes for the enslaved devices are moved to the table associated with
the VRF device. Outgoing sockets must bind to the VRF device to function.

Standard FIB rules bind the VRF device to tables and regular fib rule
processing is followed. Routed traffic through the box, is forwarded by
using the VRF device as the IIF and following the IIF rule to a table
that is mated with the VRF.

Example:

   Create vrf 1:
     ip link add vrf1 type vrf table 5
     ip rule add iif vrf1 table 5
     ip rule add oif vrf1 table 5
     ip route add table 5 prohibit default
     ip link set vrf1 up

   Add interface to vrf 1:
     ip link set eth1 master vrf1

Subject: Bluetooth: hciuart: Fix to use boolean flag with u32 type

debugfs_create_bool is asking to put u32 type pointer instead of bool
so that passing bool type with u32* cast will cause memory corruption
to read that value since it is handled by 4 bytes instead of 1 byte
inside.

Subject: iwlwifi: make sure d3_suspend/resume ops exist

We added calls to d3_suspend/resume trans ops during the
suspend/resume flow.

However, the wrapper code didn't verify the trans ops were
actually defined, resulting in panic when they were not
(such as in the case of sdio trans)

Fixes: 6dfb36c89dc2 ("iwlwifi: call d3_suspend/resume in d0i3 case as well")

Subject: iwlwifi: mvm: simplify calculating scan dwells and other timing

Remove timing values from iwl_mvm_scan_params and use defines and
arrays of values instead.

While at that fix few values and corner cases and align all OSs
to ChromeOS values.

Subject: iwlwifi: mvm: remove partial and full scan lists from lmac sched scan

Lmac sched scan supports partial scans, so we can set some channels to be
scanned on every scan iteration and others to be scanned only on some
iterations. Currently we set all channels to be scanned every iteration,
but still have some configuration of which iterations should be partial
and which should be full.

Remove all partial/full scan configuration to reduce confusions.

Subject: iwlwifi: pass NAPI struct from transport layer

The mac80211 patch to pass the NAPI struct only changed iwlwifi to
store the NAPI struct, but we can do better: pass it directly from
the lower transport layer to the opmode during RX, and then on to
mac80211 from there.

When we add multiple RX queues, we can then pass the appropriate
NAPI struct properly.

Subject: iwlwifi: convert hex_dump_to_buffer() to %*ph

There is no need to use hex_dump_to_buffer() in the cases like this:

	hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false);	/* len <= 16 */
	sprintf("%s\n", outbuf);

since it maybe easily converted to simple:

	sprintf("%*ph\n", len, buf);

Note: it seems in one case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.

Subject: iwlwifi: mvm: fix a range check in debugfs code

The &mvm->tof_data.range_req.ap[] array has IWL_MVM_TOF_MAX_APS elements
so the check should be >= instead of >.  Also the test can underflow so
I have changed "i" to unsigned.

Subject: NFC: st21nfca: fix use of uninitialized variables in error path

st21nfca_hci_load_session() calls kfree_skb() on unitialized
variables skb_pipe_info and skb_pipe_list if the call to
nfc_hci_connect_gate() failed. Reword the error path to not use
these variables when they are not initialized. While at it, there
seemed to be a memory leak because skb_pipe_info was only freed
once, after the for-loop, even though several ones were created
by nfc_hci_send_cmd.

Fixes: ec03ff1a8f9a
("NFC: st21nfca: Remove skb_pipe_list and skb_pipe_info
useless allocation")

Subject: nfc: st-nci: Add spi phy support for st21nfcb

st21nfcb does support another phy than i2c: spi.
st21nfcc does not support spi as the spi ios are used
by the AMS RF booster.

st21nfcb is not following NCI NFC Forum recommendations for spi
but rely on ST prioritary protocol ndlc as for i2c.

Subject: ath10k: wake up offchannel queue properly

Once HTT Tx queue got full offchannel queue was
stopped and never woken up again. This broke, e.g.
P2P. This could be reproduced after running a lot
of traffic enough to saturate 100% of the driver
Tx queue and then trying to send offchannel
traffic.

Subject: ath10k: wake up queue upon vif creation

Vif's vdev_id is used as queue number. However due
to the tx pausing design in ath10k it was possible
for a new interface to be created with its tx
queue stopped (via ieee80211_stop_queues). This
could in turn leave the interface inoperable until
ath10k_mac_tx_unlock() was called.

This problem only affected multi-vif scenarios when
new interfaces were created some time later after
other interfaces have been running for some time
and had Tx queue full at some point prior.

Possible manifestation of the bug was
authentication timeout for a client vif.

Subject: ath10k: fix invalid survey reporting for QCA99X0

There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with
CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.
Without this fix there will be lots of 0 msecs reported as active
and busy time.

Subject: ath10k: add cycle/rx_clear counters frequency to hw_params

The frequency at which cycle/rx_clear counters are running might
change from one target type to another. QCA99X0 is running the
counters at 150Mhz while QCA9888X and QCA6174 are running at 88Mhz.
Add a new entry to hw_params to store the target specific frequency
and use it in msecs conversion. This change fixes inconsistent
channel active/busy time.

As remain is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.

API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/wil6210/wmi.c:827
	int return assigned to unsigned long

Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,

Subject: ath10k: refactor phyerr event handlers

Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.

Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.

.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.

Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

Subject: ath10k: handle 10.4 firmware phyerr event

Header format of 10.4 firmware phyerr event is not alligned
with pre 10.4 firmware. Introduce new wmi handlers to parse
10.4 firmware specific phyerror event header.

With changes covered in this patch, radar detection works on
qca9x0 hw 2.0 which uses 10.4 firmware.

Subject: ath10k: fill in wmi 10.4 command handlers for addba/delba debug
 commands

WMI 10.4 uses the same command interface as QCA988X for addba/delba
debug wmi commands. Fill wmi_10_4_ops table with the functions used
for QCA988X for these commands.

With this change, the following debugfs entries can be used to
configure the aggregation mode and to send addba request,
addba response and delba respectively in manual aggregation mode
for QCA99X0 chip.

Subject: bnx2: Fix bandwidth allocation for some MF modes

Management firmware tells driver in case bandwidth configuration for
a specific function exists, but [regretably] the same field has different
meanings depending on the multi-function mode - it can either be
a percentile value or an actual speed.

For newer multi-function modes current logic is incorrect -
driver understands values as actual speeds instead of percentages,
causing the resulting chip configuration to be incorrect.

Subject: smsc911x: Fix crash seen if neither ACPI nor OF is configured or used

Commit 0b50dc4fc971 ("Convert smsc911x to use ACPI as well as DT") makes
the call to smsc911x_probe_config() unconditional, and no longer fails if
there is no device node. device_get_phy_mode() is called unconditionally,
and if there is no phy node configured returns an error code. This error
code is assigned to phy_interface, and interpreted elsewhere in the code
as valid phy mode. This in turn causes qemu to crash when running a
variant of realview_pb_defconfig.

	qemu: hardware error: lan9118_read: Bad reg 0x86

Subject: enic: use netdev_<foo> or dev_<foo> instead of pr_<foo>

pr_info does not give any details about the interface involved. This patch
uses netdev_info for printing the message. Use dev_info where netdev is not
ready.

Subject: enic: add devcmd2

devcmd is an interface for driver to communicate with fw/adaptor. It
involves writing data to hardware registers and waiting for the result.
This mechanism does not scale well. The queuing of "no wait" devcmds is
done in firmware memory rather than on the host. Firmware memory is a
rather more scarce and valuable resource than host memory. A devcmd storm
from one vf can disrupt the service on other pf/vf. The lack of flow
control allows for possible denial of server from one VM to another.

Devcmd2 uses work queue to post the devcmds, just like tx work queue. This
allows better flow control.

Initialize devcmd2, if fails we fall back to devcmd1.

Also change the driver version.

Subject: net/mlx5e: Make RSS indirection table size a constant

The indirection table size was defined by a variable that
was actually assigned a constant value.
Since we do not have any forseen intension to make it configurable
we simply made it a constant.

We also limit the number of channels such that the RSS indirection
table could always populate all RX rings.

Subject: net/mlx5e: Support smaller RX/TX ring sizes

We un-intentionally limited the minimum rings size too much.

TX minimum ring size reduced from 128 to 64.
RX minimum ring size reduced from 128 to 2.

Subject: net/mlx5e: Ethtool link speed setting fixes

- Port speed settings are applied by the device only upon
  port admin status transition from DOWN to UP.
  So we enforce this transition regardless of the port's
  current operation state (which may be occasionally DOWN if
  for example the network cable is disconnected).
- Fix the PORT_UP/DOWN device interface enum
- Set the local_port bit in the device PAOS register
- EXPORT the PAOS (Port Administrative and Operational Status)
  register set/query access functions.

Subject: rtlwifi: rtl8192cu: remove duplicated routine in hw.c and mac.c

rtl92c_set_xxx_filter is same routine with rtl92cu_set_hw_reg.
so i remove those functions that are rtl92c_set_xxx_filter.
(rtl92c_get_xxx_filter is also same reason.)
also i add code updating struct rtl_mac member variable in the
rtl92cu_set_hw_reg.
after that, no more _update_mac_setting is not useful. thus i remove that.

Subject: rtlwifi: rtl8192cu: Remove and replace routine in hw.c and mac.c

I remove duplicated routines which related rtl92cu_set_hw_reg().

1. rtl92c_set_qos() and HW_VAR_AC_PARAM routine are similar code.
so i replace code with rtlpriv->cfg->ops->set_hw_reg().

2. rtl92c_set_mac_addr() and 'HW_VAR_ETHER_ADDR' case at
rtl92cu_set_hw_reg() routine are similar code.
so i removed rtl92c_set_mac_addr() function.
also it was not used anywhere.

3. remove HW_VAR_ACM_CTRL routine in rtl92cu_set_hw_reg().
if rtl_usb->acm_method is not EACMWAY2_SW, HW_VAR_ACM_CTRL is called
from HW_VAR_AC_PARAM. but it never called. because acm_method is always
EACMWAY2_SW. so i remove acm_method check routine
and HW_VAR_ACM_CTRL routine.

both usb and pci interface is not used HW_VAR_ACM_CTRL.
but i can't test pci interface module, so i didn't modify pci code.

drivers/net/wireless/mwl8k.c: In function ‘mwl8k_bss_info_changed’:
drivers/net/wireless/mwl8k.c:3290:2: warning: ‘ap_mcs_rates’ may be used uninitialized in this function [-Wmaybe-uninitialized]

  ^
drivers/net/wireless/mwl8k.c:4987:5: note: ‘ap_mcs_rates’ was declared here
  u8 ap_mcs_rates[16];
     ^

The warning was bogus.  But the conditionals were rather complicated,
with multiple redundant checks.  This consolidates the checking and
makes it more readable IMHO.

Subject: rt2x00: adjust EEPROM_SIZE for rt2500usb

rt2500usb_validate_eeprom() read data up to 0x6e (EEPROM_CALIBRATE_OFFSET)
but only 0x6a bytes has been allocated and read from the eeprom.

This lead to out-of-bound accesses and invalid values for
EEPROM_BBPTUNE_R17 and EEPROM_CALIBRATE_OFFSET.

Change the EEPROM_SIZE to 0x6e in order to retrieve all the fields.

Tested with a rt2570 device.

Subject: iwlwifi: rs: disable MIMO only if allowed in configuration

Fix bug where MIMO is disabled for low latency TX on P2P VIF
regardless of configuration. Make it dependent on
IWL_MVM_RS_DISABLE_P2P_MIMO compilation option. Change configuration
so that MIMO will be disabled only in SDIO platforms.

Both loops of this function compare data from the 'chan' array and then
check if the index is valid.

The 2 conditions should be inverted to avoid an out-of-bounds access.

Subject: iwlwifi: mvm: don't disconnect on beacon loss in D0I3

Currently if we wake up during D0I3 due to beacon loss we disconnect
immediately. This behaviour causes redundant disconnection, which could
be prevented by polling as it is usually done in mac80211.
Instead, we prefer reporting beacon loss and let mac80211 try polling
before disconnection.

Subject: iwlwifi: mvm: fix a race in D0i3 vs. Tx path

When we enter D0i3, we must stop TXing otherwise the
sequence number we use might conflict with the firmware's
internal TX. In order to do so, we have
IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we
enter D0i3. There is a bug in this code since we may Tx even
if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as
mvm->d0i3_ap_sta_id is not set.

To make sure that we don't have any packet in the Tx path
while we set mvm->d0i3_ap_sta_id, call synchronize_net only
after we already set mvm->d0i3_ap_sta_id.

Subject: igb: Fix oops caused by missing queue pairing

When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is
set if adapter->rss_queues exceeds half of max_rss_queues in
igb_init_queue_configuration().
On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of
queues exceeds half of max_combined in igb_set_channels() when changing
the number of queues by "ethtool -L".
In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size
of adapter->msix_entries[], an overflow can occur in
igb_set_interrupt_capability(), which in turn leads to an oops.

Fix this problem as follows:
 - When changing the number of queues by "ethtool -L", set
   IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver.
 - When increasing the size of q_vector, reallocate it appropriately.
   (With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.)

Another possible way to fix this problem is to cap the queues at its
initial number, which is the number of the initial online cpus. But this
is not the optimal way because we cannot increase queues when another
cpu becomes online.

Note that before commit cd14ef54d25b ("igb: Change to use statically
allocated array for MSIx entries"), this problem did not cause oops
but just made the number of queues become 1 because of entering msi_only
mode in igb_set_interrupt_capability().

Fixes: 907b7835799f ("igb: Add ethtool support to configure number of channels")

Subject: igb: do not re-init SR-IOV during probe

During driver probing the following code path is triggered.
igb_probe
->igb_sw_init
  ->igb_probe_vfs
    ->igb_pci_enable_sriov
      ->igb_sriov_reinit

Doing the SR-IOV re-init is not necessary during probing since we're
starting from scratch. Here we can call igb_enable_sriov() right away.

Running igb_sriov_reinit() during igb_probe() also seems to cause
occasional packet loss on some onboard 82576 NICs. Reproduced on
Dell and HP servers with onboard 82576 NICs.
Example:
Intel Corporation 82576 Gigabit Network Connection [8086:10c9] (rev 01)
Subsystem: Dell Device [1028:0481]

Subject: igb: implement high frequency periodic output signals

In addition to interrupt driven target time output events, the i210
also has two programmable clock outputs.  These clocks support periods
between 16 nanoseconds and 140 milliseconds.  This patch implements
the periodic output function using the clock outputs when possible,
falling back to the target time for longer periods.

Subject: igb: Teardown SR-IOV before unregister_netdev()

When the .remove() callback for a PF is called, SR-IOV support for the
device is disabled, which requires unbinding and removing the VFs.
The VFs may be in-use either by the host kernel or userspace, such as
assigned to a VM through vfio-pci.  In this latter case, the VFs may
be removed either by shutting down the VM or hot-unplugging the
devices from the VM.  Unfortunately in the case of a Windows 2012 R2
guest, hot-unplug is broken due to the ordering of the PF driver
teardown.  Disabling SR-IOV prior to unregister_netdev() avoids this
issue.

Subject: e100: Add a check after pci_pool_create to avoid null pointer
 dereference

The driver lacks the check of nic->cbs_pool after pci_pool_create
in e100_probe. When this function is failed, a null pointer dereference
occurs when pci_pool_alloc uses nic->cbs_pool in e100_alloc_cbs.
This patch adds a check and related error handling code to fix it.

Subject: e1000e: Modify Tx/Rx configurations to avoid null pointer
 dereferences in e1000_open

When e1000e_setup_rx_resources is failed in e1000_open,
e1000e_free_tx_resources in "err_setup_rx" segment is executed.
"writel(0, tx_ring->head)" statement in e1000_clean_tx_ring
in e1000e_free_tx_resources will cause a null poonter dereference(crash),
because "tx_ring->head" is only assigned in e1000_configure_tx
in e1000_configure, but it is after e1000e_setup_rx_resources.

This patch moves head/tail register writing to e1000_configure_tx/rx,
which can fix this problem. It is inspired by igb_configure_tx_ring
in the igb driver.

Specially, thank Alexander Duyck for his valuable suggestion.

Simplify port-specific macros by eliminating explicit comparison
with 0. More importantly, enclose formal parameter in parens to
eliminate the risk of an operator precedence surprise.

Subject: dsa: mv88e6xxx: Set DSA mode based on chip abilities

Older devices only support a single DSA frame format, where as newer
devices have two. Take this into account when configuring a DSA port.
The port needs to be in plain old DSA mode, since this is a DSA link,
where as the newer format can be used for the CPU port.

Subject: bnx2x: Add vxlan RSS support

Latest FW submission added some vxlan offload capabilities to our device.
This patch adds the ability to connect to the vxlan NDOs and configure
the UDP port associated with it in the HW.

The device would now be capable of performing RSS according to the
inner headers of the vxlan packets.

Subject: cxgb4: memory corruption in debugfs

You can't use kstrtoul() with an int or it causes memory corruption.
Also j should be unsigned or we have underflow bugs.

I considered changing "j" to unsigned long but everything fits in a u32.

Subject: ath10k: ensure pktlog disable cmd reaches fw before pdev suspend

Found incorrect sequence in ath10k_core_stop() where wmi pktlog
disable cmd is passed from ath10k_debug_stop() to firmware
immediately after wmi pdev suspend cmd. Firmware will not accept
any wmi cmd after receiving wmi pdev suspend cmd.

Fix this issue in ath10k_core_stop() by moving ath10k_debug_stop()
just before sending pdev suspend cmd. So that pktlog disable cmd
will get passed before pdev suspend cmd.

Subject: NFC: trf7970a: Add NULL check to clear up smatch warning

Although it should be unnecessary, add a NULL pointer check
to trf7970a_send_upstream() to eliminate a smatch warning.

Subject: can: flexcan: demote register output to debug level

This message isn't really helpful for the general reader of the kernel
logs, so should not be printed with info level. All other register
programming outputs in the flexcan driver already use the debug level.

From 57b8efa1a5e4baf3dfca8d5d7bfb946bd44ff390 Mon Sep 17 00:00:00 2001
From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>
Date: Wed, 19 Aug 2015 06:12:29 +0300
Subject: vrf: plug skb leaks

Currently whenever a packet different from ETH_P_IP is sent through the
VRF device it is leaked so plug the leaks and properly drop these
packets.

Subject: vrf: don't panic on cache create failure

It's pointless to panic on cache create failure when that case is handled
and even more so since it's not a kernel-wide fatal problem so don't
panic.

Subject: vrf: move vrf_insert_slave so we can drop a goto label

We can simplify do_vrf_add_slave by moving vrf_insert_slave in the end
of the enslaving and thus eliminate an error goto label. It always
succeeds and isn't needed before that anyway.

When ndo_add|del_slave ops are used, they're taken from the respective
master device's netdev ops, so if the master device is a VRF only then
the VRF ops will get called thus no need to check the type of the
master.

Subject: device property: Add ETH_ALEN check, update comments.

This patch adds MAC address length check back into
the device_get_mac_addr() function before calling
is_valid_ether_addr() similar to the way the OF
routine does it.

Update the comments for the two new functions.

Subject: smsc911x: Remove dev==NULL check.

The dev==NULL check in smsc911x_probe_config is useless
and isn't providing any additional protection. If a fwnode
doesn't exist then an appropriate error should be returned
by device_get_phy_mode() covering the original case
of a missing of/fwnode.

Add the IPv6 addresses as an union with IPv4 ones. When using IPv4, the
newly introduced padding after the IPv4 addresses needs to be zeroed out.

Subject: ip_tunnels: use tos and ttl fields also for IPv6

Rename the ipv4_tos and ipv4_ttl fields to just 'tos' and 'ttl', as they'll
be used with IPv6 tunnels, too.

Subject: route: move lwtunnel state to dst_entry

Currently, the lwtunnel state resides in per-protocol data. This is
a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice versa).
The xmit function of the tunnel does not know whether the packet has been
routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the
lwtstate data to dst_entry makes such inter-protocol tunneling possible.

As a bonus, this brings a nice diffstat.

Subject: iwlwifi: mvm: catch underflow error earlier

My static checker complains that we don't check for underflows in
iwl_dbgfs_fw_dbg_conf_write().  This is harmless because we have a
sanity check in iwl_mvm_start_fw_dbg_conf(), but we may as well make
this unsigned and silence the underflow warning.

Subject: iwlwifi: correctly size command string arrays

The command string array is assumed to be indexable by a full u8, so it
must have 256 entries (0-255), not just 255. A recent firmware change
(apparently) started using the command 0xff for a notification to the
host, causing the driver to crash in debug message/tracing code.

TX power limits) but makes the code compatible with newer firmware
images expecting the larger command.

Subject: net: dsa: mv88e6xxx: set 802.1Q mode to Fallback

The current Secure port mode requires the port-based VLANs to also be
valid in the 802.1Q VLAN Table Unit. The current hardware bridging
support only configures the port-based VLANs, thus is broken.

A new patchset is required to adapt the hardware bridging code to fully
support the Secure port mode.

In the meantime, change the 802.1Q mode of every ports to Fallback,
which filtering is more permissive, and doesn't add this restriction to
handle port-based and tagged-based VLANs.

Subject: gro: Fix remcsum offload to deal with frags in GRO

The remote checksum offload GRO did not consider the case that frag0
might be in use. This patch fixes that by accessing headers using the
skb_gro functions and not saving offsets relative to skb->head.

Subject: vxlan: GRO support at tunnel layer

Add calls to gro_cells infrastructure to do GRO when receiving on a tunnel.

Testing:

Ran 200 netperf TCP_STREAM instance

  - With fix (GRO enabled on VXLAN interface)

    Verify GRO is happening.

    9084 MBps tput
    3.44% CPU utilization

Subject: NET: nps_enet: replace use of cause register

When interrupt is received we read directly from control
register for RX/TX instead of reading cause register
since this register fails to indicate TX done when
TX interrupt is "edge mode".

Subject: NET: nps_enet: TX done race condition

We need to set tx_skb pointer before send frame.
If we receive interrupt before we set pointer we will try
to free SKB with wrong pointer.
Now we are sure that SKB pointer will never be NULL during
handling TX done and check is removed.

Subject: fjes: Introduce FUJITSU Extended Socket Network Device driver

This patch adds the basic code of FUJITSU Extended Socket
Network Device driver.

When "PNP0C02" is found in ACPI DSDT, it evaluates "_STR"
to check if "PNP0C02" is for Extended Socket device driver
and retrieves ACPI resource information. Then creates
platform_device.

Subject: fjes: platform_driver's .probe and .remove routine

This patch implements platform_driver's .probe and .remove
routine, and also adds board specific private data structure.

This driver registers net_device at platform_driver's .probe
routine and unregisters net_device at its .remove routine.

Subject: fjes: raise_intr_rxdata_task

This patch add raise_intr_rxdata_task.
Extended Socket Network Device is shared memory
based, so someone's transmission denotes other's
reception. In order to notify receivers, sender
has to raise interruption of receivers.
raise_intr_rxdata_task does this work.

Subject: fjes: tx_stall_task

This patch adds tx_stall_task.
When receiver's buffer is full, sender stops
its tx queue. This task is used to monitor
receiver's status and when receiver's buffer
is avairable, it resumes tx queue.

Subject: ath9k_htc: do ani shortcalibratio if we got -ETIMEDOUT

current code will handle -ETIMEDOUT as success which is probalbly wrong.

According to this comment I assume it is safe to handle -ETIMEDOUT as false:
drivers/net/wireless/ath/ath9k/calib.c
290         /*
291          * We timed out waiting for the noisefloor to load, probably due to an
292          * in-progress rx. Simply return here and allow the load plenty of time
293          * to complete before the next calibration interval.  We need to avoid
294          * trying to load -50 (which happens below) while the previous load is
295          * still in progress as this can cause rx deafness. Instead by returning
296          * here, the baseband nf cal will just be capped by our present
297          * noisefloor until the next calibration timer.
298          */

Since no other error wariants are present, this patch is checking only
for (ret <= 0).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Broadcom is working on better reflection of interface combinations. With
upcoming patches we may have 1st combination supporting less interfaces
than others.
To don't run out of addresses check all combinations to find the one
with the greatest max_interfaces value.

Subject: brcmfmac: block the correct flowring when backup queue overflow

brcmf_flowring_block blocks the last active flowring under the same
interface instead of the one provided by caller. This could lead to a
dead lock of netif stop if there are more than one flowring under the
interface and the traffic is high enough so brcmf_flowring_enqueue can
not unblock the ring right away.

Subject: brcmfmac: bump highest event number for 4339 firmware

The event mask length is determined by the highest event number
that is specified in the driver. When this length is shorter than
firmware expects setting event mask will fail and device becomes
pretty useless. This issue was reported with bcm4339 firmware that
was recently released.

Subject: brcmfmac: Add support for host platform NVRAM loading.

Host platforms such as routers supported by OpenWRT can
support NVRAM reading directly from internal NVRAM store.
With this patch the nvram load routines will fall back to
this method when there is no nvram file and support is
available in the kernel.

Commit 5d5cd85ff441 ("rsi: Fix failure to load firmware after memory
leak fix and fix the leak") also added a check on the allocation of
DMA-accessible memory that may directly return. In that case the
already allocated firmware data is leaked. Make sure the data is
always freed correctly. Detected by Coverity CID 1316519.

Subject: net/mlx5e: Avoid accessing NULL pointer at ndo_select_queue

To avoid multiply/division operations on the data path,
we hold a {channel, tc}==>txq mapping table.
We held this mapping table inside the channel object that is
being destroyed upon some configuration operations (e.g MTU change).
So in case ndo_select_queue occurs during such a configuration operation,
it may access a NULL channel pointer, resulting in kernel panic.
To fix this issue we moved the {channel, tc}==>txq mapping table
outside the channel object so that it will be available also
during such configuration operations.

Subject: ppp: implement x-netns support

Let packets move from one netns to the other at PPP encapsulation and
decapsulation time.

PPP units and channels remain in the netns in which they were
originally created. Only the net_device may move to a different
namespace. Cross netns handling is thus transparent to lower PPP
layers (PPPoE, L2TP, etc.).

PPP devices are automatically unregistered when their netns gets
removed. So read() and poll() on the unit file descriptor will
respectively receive EOF and POLLHUP. Channels aren't affected.

Subject: r8169: Add values missing in @get_stats64 from HW counters

The r8169 driver collects statistical information returned by
@get_stats64 by counting them in the driver itself, even though many
(but not all) of the values are already collected by tally counters
(TCs) in the NIC.  Some of these TC values are not returned by
@get_stats64.  Especially the received multicast packages are missing
from /proc/net/dev.

Rectify this by fetching the TCs and returning them from
rtl8169_get_stats64.

The counters collected in the driver obviously disappear as soon as the
driver is unloaded so after a driver is loaded the counters always start
at 0. The TCs on the other hand are only reset by a power cycle.  Without
further considerations the values collected by the driver would not match
up against the TC values.

This patch introduces a new function rtl8169_reset_counters which
resets the TCs.  Also, since rtl8169_reset_counters shares most of
its code with rtl8169_update_counters, refactor the shared code into
two new functions  rtl8169_map_counters and rtl8169_unmap_counters.

Unfortunately chip versions prior to RTL_GIGA_MAC_VER_19 don't allow
to reset the TCs programatically.  Therefore introduce an addition to
the rtl8169_private struct and a function rtl8169_init_counter_offsets
to store the TCs at first rtl_open.  Use these values as offsets in
rtl8169_get_stats64.  Propagate a failure to reset *and* update the
counters up to rtl_open and emit a warning message, if so.

Subject: ath10k: add spectral scan support for 10.4 fw

To enable/configure spectral scan parameters in 10.4 firmware, existing
wmi spectral related functions can be reused. Link those functions in
10.4 wmi ops table.

In addition, adjust bin size (only when size is 68 bytes) before reporting
bin samples to user space. The background for this adjustment is that
qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
carries band edge detection data (+32) mainly used in radar detection
purpose. Additional last 4 bytes are stripped to make bin size valid one.

This bin size adjustment will happen only for qca99x0, all other chipsets
will report proper bin sizes (64/128) without extra 4 bytes being added
at the end. The changes are validated in qca99x0 using 10.4 firmware.

Subject: ath10k: add qca6164 support

This adds additional 0x0041 PCI Device ID
definition to ath10k for QCA6164 which is a 1
spatial stream sibling of the QCA6174 (which is 2
spatial stream chip).

The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump
will look like this:

 ath10k_pci 0000:02:00.0: firmware register dump:
 ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 0x00955B31
 ...

Note the value 0x000A012D.

Special credit goes to Alan Liu
<alanliu@qca.qualcomm.com> for providing support
help which enabled me to come up with this patch.

Subject: i40e: don't degrade __le16

Sparse cries when we compare an __le16 to a u16, almost like it cares
about architectures other than x86. Weird. Use the le16_to_cpu macro to
make it stop crying.

Subject: i40e: Fix legacy interrupt mode in the driver

This patch fixes the driver flow to take into account legacy interrupts.
Over time we added code that assumes MSIX is the only mode that the
driver runs in. It also enables a legacy workaround to trigger SWINT
when the TX ring has non-cache aligned descriptors pending and interrupts
are disabled.

We work with a single vector in MSI mode too, so apply the same
restrictions as Legacy.

Subject: i40e: Fix comment for ethtool diagnostic link test

The existing comment is incorrect.  Add new comment to point out that the
PF reset does not affect link but if the reset is changed to a different
type that does affect link then the link test would need to be moved to
before the reset.

Subject: i40evf: Remove PF specific register definitions from the VF

There were quite a few issues when the wrong defines were getting used
in the VF driver. This patch fixes the code where PF driver registers
were getting used for VF driver, and also removes the registers that are
not being used from the VF register file.

Subject: i40e: Remove redundant and unneeded messages

The kernel notifies all VXLAN capable registered drivers, i.e. any
driver that implements ndo_add_vxlan_port(), of the addition of a
port so that the driver can track which ports are in use.  There's
no need to log this - it just fills the system log with useless and
irksome noise.

Also, when failing to init SR-IOV interfaces the driver was printing the
same message twice. Just remove the inner printk and let the outer message
catch enable as well as the other failures.

Subject: bgmac: support up to 3 cores (devices) on a bus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Broadcom buses may have more than 1 Ethernet device. This is used e.g.
to have few interfaces connected to different switch ports. So far we
saw chipsets with only 2 devices (e.g. BCM4706) but recent ones have
up to 3 (e.g. Netgear R8000 uses 3rd interface for most of switch
traffic, lower interfaces are for some kind of offloading).

No pr_dbg method exists.

While this code is #if 0'd, it'd be nicer to
use the generic hex_dump, so use it instead.

Subject: smsc911x: Ignore error return from device_get_phy_mode()

Commit 62ee783bf1f8 ("smsc911x: Fix crash seen if neither ACPI nor OF is
configured or used") introduces an error check for the return value from
device_get_phy_mode() and bails out if there is an error. Unfortunately,
there are configurations where no phy is configured. Those configurations
now fail.

To fix the problem, accept error returns from device_get_phy_mode(),
and use the return value from device_property_read_u32() to determine
if there is a suitable firmware interface to read the configuration.

Subject: geneve: Add support to collect tunnel metadata.

Following patch create new tunnel flag which enable
tunnel metadata collection on given device. These devices
can be used by tunnel metadata based routing or by OVS.
Geneve Consolidation patch get rid of collect_md_tun to
simplify tunnel lookup further.

Subject: geneve: Consolidate Geneve functionality in single module.

geneve_core module handles send and receive functionality.
This way OVS could use the Geneve API. Now with use of
tunnel meatadata mode OVS can directly use Geneve netdevice.
So there is no need for separate module for Geneve. Following
patch consolidates Geneve protocol processing in single module.

Subject: virtio-net: avoid unnecessary sg initialzation

Usually an skb does not have up to MAX_SKB_FRAGS frags. So no need to
initialize the unuse part of sg. This patch initialize the sg based on
the real number it will used:

- during xmit, it could be inferred from nr_frags and can_push.
- for small receive buffer, it will also be 2.

Subject: rocker: use change upper info

Since now information about changed upper is passed along, benefit from
that and use this info directly.

This also fixes possible issues that could happen when non-master device
is added (current code does not distinguish between master and non-master
upper device).

Subject: mlxsw: Make mailboxes 4KB aligned

The HW-SW contract requires mailboxes passed to the firmware to be 4KB
aligned. Previously, these mailboxes were mapped using streaming DMA
routines, which do not guarantee the bus addresses to be 4KB aligned.
Under certain conditions this constraint was indeed violated and errors
were observed.

By using consistent DMA mapping routines together with a mailbox size of
4KB we are guaranteed not to violate the constraint.

Subject: net/mlx4_core: Capping number of requested MSIXs to MAX_MSIX

We currently manage IRQs in pool_bm which is a bit field
of MAX_MSIX bits. Thus, allocating more than MAX_MSIX
interrupts can't be managed in pool_bm.
Fixing this by capping number of requested MSIXs to
MAX_MSIX.

Subject: Bluetooth: hci_intel: Add Intel baudrate configuration support

Implement the set_baudrate callback for hci_intel.
 - Controller requires a read Intel version command before updating
   its baudrate.
 - The operation consists in an async cmd since the controller does
   not respond at the same speed.
 - Wait 100ms to let the controller change its baudrate.
 - Clear RTS until we change our own UART speed

Manage speed change in the setup function, we need to restore the oper
speed once chip has booted on patched firmware.

Subject: Bluetooth: hci_intel: Add support for platform driver

A platform device can be used to provide some specific resources in
order to manage the controller. In this first patch we retrieve the
reset gpio which is used to power on/off the controller.

The main issue is to match the current tty with the correct pdev.
In case of ACPI, we can easily find the right tty/pdev pair because
they are both child of the same UART port.

If controller is powered-on from the driver, we need to wait for a
HCI boot event before being able to send any command.

Subject: Bluetooth: hci_bcm: Fix crash on suspend

If bcm_suspend is called whithout device opened there is a crash as
it tries to use bdev->hu which is NULL.
Rename bcm_device_list_lock to bcm_device_lock as it does not only apply
to bcm_device_list.

Subject: r8169: Add software counter for multicast packages

The multicast hardware counter on 8168/8111 chips is only 32 bit while the
statistics in struct rtnl_link_stats64 are 64 bit.  Given that statistics
are requested on an irregular basis, an overflow of the hardware counter
can go unnoticed.  To count even very large numbers of multicast packets
reliably, add a software counter and remove previously applied code to
fill the multicast field requested by @rtl8169_get_stats64 with the values
read from the rx_multicast hardware counter.

The change to use a custom dst broke tcpdump captures on the VRF device:

Local packets going through the VRF device are missing an ethernet header.
Fix by adding one and then stripping it off before pushing back to the IP
stack. With this patch you get the expected dumps:

Subject: cxgb4: Force uninitialized state if FW in adapter is unsupported

Forcing uninitialized state allows us to upgrade and reinitialize
the adapter.

    FW_VERSION_T4 = 1.4.0.0
    FW_VERSION_T5 = 0.0.0.0
    FW_VERSION_T6 = 0.0.0.0
At this point driver supports above and greater than above version.

If FW in adapter < min FW_VERSION driver supports tries to upgrade the FW
If FW in adapter >= FW_VERSION driver supports then it follows normal path

From b0fbdae127a3968688ff7b474e9164dc4bf30dd5 Mon Sep 17 00:00:00 2001
From: Shradha Shah <sshah@solarflare.com>
Date: Fri, 28 Aug 2015 10:55:42 +0100
Subject: sfc: Allow driver to cope with a lower number of VIs than it needs
 for RSS

Previously, the driver would refuse to load if it couldn't secure
enough VIs from the MC to fulfill its RSS requirements.
This was causing probe to fail on later functions in
configurations where we'd run out of VIs, such as having many
VFs.

This change allows the driver to load with fewer VIs, down to a
minimum of 2. A warning will be printed saying that RSS
requirements were not met, possibly affecting performance.

efx->max_tx_channels needs to be set to avoid going down the
failure path in efx_probe_nic() immediately in the loop after the
probe() NIC-type function.
Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack
of VIs.

Fix scripts/checkpatch.pl's messages like:

BTW, it doesn't detect the reversed comparisons (which I've fixed as well).

Subject: ravb: propagate platform_get_irq() error upstream

The driver overrides the error returned by platform_get_irq() with -ENODEV
which e.g. precludes the deferred  probing from working. Propagate the real
error code to the driver core instead.

Subject: bonding: fix bond_poll_controller bh_enable warning

The problem is rcu_read_unlock_bh() which triggers a warning when irqs are
disabled. ndo_poll_controller should run with irqs disabled always so we
can drop the rcu_read_lock_bh.

Subject: ip_tunnels: convert the mode field of ip_tunnel_info to flags

The mode field holds a single bit of information only (whether the
ip_tunnel_info struct is for rx or tx). Change the mode field to bit flags.
This allows more mode flags to be added.

Subject: ip_tunnels: record IP version in tunnel info

There's currently nothing preventing directing packets with IPv6
encapsulation data to IPv4 tunnels (and vice versa). If this happens,
IPv6 addresses are incorrectly interpreted as IPv4 ones.

Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store this
in ip_tunnel_info. Reject packets at appropriate places if they are supposed
to be encapsulated into an incompatible protocol.

Subject: vxlan: do not receive IPv4 packets on IPv6 socket

By default (subject to the sysctl settings), IPv6 sockets listen also for
IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in
packets received through an IPv6 socket.

In addition, it's currently not possible to have both IPv4 and IPv6 vxlan
tunnel on the same port (unless bindv6only sysctl is enabled), as it's not
possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's
no way to specify both IPv4 and IPv6 remote/group IP addresses.

Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not
done globally in udp_tunnel, as l2tp and tipc seems to work okay when
receiving IPv4 packets on IPv6 socket and people may rely on this behavior.
The other tunnels (geneve and fou) do not support IPv6.

Subject: net/smsc911x: Fix deferred probe for interrupt

The interrupt handler may not be available when smsc911x probes if the
interrupt handler is a GPIO controller for example. Let's fix that
by adding handling for -EPROBE_DEFER.

Subject: geneve: Use GRO cells infrastructure.

Geneve can benefit from GRO at the device level in a manner similar
to other tunnels, especially as hardware offloads are still emerging.

After this patch, aggregated frames are seen on the tunnel interface.
Single stream throughput nearly doubles in ideal circumstances (on
old hardware).

Subject: net: thunderx: Receive hashing HW offload support

Adding support for receive hashing HW offload by using RSS_ALG
and RSS_TAG fields of CQE_RX descriptor. Also removed dependency
on minimum receive queue count to configure RSS so that hash is
always generated.

This hash is used by RPS logic to distribute flows across multiple
CPUs. Offload can be disabled via ethtool.

Subject: net: thunderx: Support for HW VLAN stripping

This patch configures HW to strip 802.1Q header if found in a
receiving packet. The stripped VLAN ID and TCI information is
passed on to software via CQE_RX. Also sets netdev's 'vlan_features'
so that other HW offload features can be used for tagged packets.

This offload feature can be enabled or disabled via ethtool.

Network stack normally ignores RPS for 802.1Q packets and hence low
throughput. With this offload enabled throughput for tagged packets
will be almost same as normal packets.

Note: This patch doesn't enable HW VLAN insertion for transmit packets.

Subject: net: thunderx: Rework interrupt handling

Rework interrupt handler to avoid checking IRQ affinity of
CQ interrupts. Now separate handlers are registered for each IRQ
including RBDR. Register interrupt handlers for only those
which are being used. Add nicvf_dump_intr_status() and use it
in irq handlers.

Subject: net: thunderx: Support for upto 96 queues for a VF

This patch adds support for handling multiple qsets assigned to a
single VF. There by increasing no of queues from earlier 8 to max
no of CPUs in the system i.e 48 queues on a single node and 96 on
dual node system. User doesn't have option to assign which Qsets/VFs
 to be merged. Upon request from VF, PF assigns next free Qsets as
secondary qsets. To maintain current behavior no of queues is kept
to 8 by default which can be increased via ethtool.

If user wants to unbind NICVF driver from a secondary Qset then it
should be done after tearing down primary VF's interface.

From d77a2384988fd397cf4f71417b9d971aa435758d Mon Sep 17 00:00:00 2001
From: Sunil Goutham <sgoutham@cavium.com>
Date: Sun, 30 Aug 2015 12:29:16 +0300
Subject: net: thunderx: Support for internal loopback mode

Support for setting VF's corresponding BGX LMAC in internal
loopback mode. This mode can be used for verifying basic HW
functionality such as packet I/O, RX checksum validation,
CQ/RBDR interrupts, stats e.t.c. Useful when DUT has no external
network connectivity.

'loopback' mode can be enabled or disabled via ethtool.

Note: This feature is not supported when no of VFs enabled are
morethan no of physical interfaces i.e active BGX LMACs

From 4c22279848c531fc7f555d463daf3d0df963bd41 Mon Sep 17 00:00:00 2001
From: Pravin B Shelar <pshelar@nicira.com>
Date: Sun, 30 Aug 2015 18:09:38 -0700
Subject: ip-tunnel: Use API to access tunnel metadata options.

Currently tun-info options pointer is used in few cases to
pass options around. But tunnel options can be accessed using
ip_tunnel_info_opts() API without using the pointer. Following
patch removes the redundant pointer and consistently make use
of API.

Subject: net: phy: Allow PHY devices to identify themselves as Ethernet
 switches, etc.

Some Ethernet MAC drivers using the PHY library require the hardcoding
of link parameters when interfaced to a switch device, SFP module,
switch to switch port, etc. This has typically lead to various ad-hoc
implementations looking like this:

- using a "fixed PHY" emulated device, which will provide link
  indication towards the Ethernet MAC driver and hardware

- pretend there is no PHY and hardcode link parameters, ala mv643x_eth

Based on that, it is desireable to have the PHY drivers advertise the
correct link parameters, just like regular Ethernet PHYs towards their
CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able
to tell whether this link should be monitored or not. In the context
of an Ethernet switch, SFP module, switch to switch link, we do not
need to monitor this link since it should be always up.

Subject: dsa: mv88e6xxx: Allow speed/duplex of port to be configured

The current code sets user ports to perform auto negotiation using the
phy. CPU and DSA ports are configured to full duplex and maximum speed
the switch supports.

There are however use cases where the CPU has a slower port, and when
user ports have SFP modules with fixed speed. In these cases, port
settings to be read from a fixed_phy devices. The switch driver then
needs to implement the adjust_link op, so the port settings can be
set.

Subject: phy: fixed_phy: Set supported speed in phydev

Set the supported field of the phydev to indicate the speed features
of the phy. If the phy is never attached to a netdev, but used in an
adjust_link() function, the speed will be incorrectly evaluated to
10/half rather than the correct speed/duplex.

Subject: dsa: mv88e6xxx: Set the RGMII delay based on phy interface

Some Marvell switches allow the RGMII Rx and Tx clock to be delayed
when the port is using RGMII. Have the adjust_link function look at
the phy interface type and enable this delay as requested.

Subject: net: phy: fixed_phy: Set phy capabilities even when link down.

What features a phy supports is masked in genphy_config_init() by
looking at the PHYs BMSR register.

If the link is down, fixed_phy_update_regs() will only set the auto-
negotiation capable bit in BMSR. Thus genphy_config_init() comes to
the conclusion the PHY can only perform 10/Half, and masks out the
higher speed features. If however the link it up, BMSR is set to
indicate the speed the PHY is capable of auto-negotiating, and
genphy_config_init() does not mask out the high speed features.

To fix this, when the link is down, have fixed_phy_update_regs() leave
the link status, auto-negotiation complete, and link partner
capabilities unset, but set all the local capabilities depending on
the fixed phy speed.

Subject: phylib: fix device deletion order in mdiobus_unregister()

commit 8b63ec1837fa ("phylib: Make PHYs children of their MDIO bus, not
the bus' parent.") uncovered a problem in mdiobus_unregister() which
leads to this warning when I reboot an APM Mustang (arm64) platform:

The problem is that mdiobus_unregister() deletes the bus device before
unregistering the phy devices on the bus. This wasn't a problem before
because the phys were not children of the bus:

  /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
  /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0

But now that they are:

  /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03

when mdiobus_unregister deletes the bus device, the phy subdirs are
removed from sysfs also. So when the phys are unregistered afterward,
we get the warning. This patch changes the order so that phys are
unregistered before the bus device is deleted.

Subject: i40e: Set defport behavior for the Main VSI when in promiscuous mode

This fixes bugs where the port is not receiving multicast or VLAN tagged
packets when in promiscuous mode. This can occur when a SW bridge is
created on top of the device.

This also fixes issues where the promiscuous behavior setting was not
being preserved across a reset caused by features being enabled or
disabled.

We are using defport instead of doing a true promiscuous mode because we do
not need to receive the SRIOV or VMDq VSI directed traffic which would suck
up bandwidth and is really not intended for the SW bridge.

In addition, with defport we get VLAN promiscuous behavior which is not
possible from the VSI level promiscuous setting.

There are various reasons why this method may or may not need to be

Subject: ixgbe: Add support for UDP-encapsulated tx checksum offload

By using GSO for UDP-encapsulated packets, all ixgbe devices can
be directed to generate checksums for the inner headers because
the outer UDP checksum can be zero. So point the machinery at the
inner headers and have the hardware generate the checksum.

Subject: ixgbe: Add support for entering low power link up state

When the device is closing or suspending, call ixgbe_enter_lplu to
enter low power link up state on devices that support it. When this
is done, prevent the phy from being reset in the ixgbe_down path
so that link is present when calling ixgbe_enter_lplu.

Subject: ixgbe: add get_bus_info method for X550

Added ixgbe_get_bus_info_X550em to X550 code. ixgbe_get_bus_info_X550em
sets bus.width to ixgbe_bus_width_unknown and bus.speed to
ixgbe_bus_speed_unknown, because IOSF does not report a PCIe bus
width or speed.

Subject: ixgbe: add new bus type for intergrated I/O interface (IOSF)

With this patch we add support for a new bus type ixgbe_bus_type_internal.
X550em devices use IOSF and not PCIe bus so this new type is to accommodate
them.

Subject: ixgbe: Remove unused PCI bus types

The ixgbe never has as very doubtfully ever will support either
PCI or PCI-X devices.  So remove the unused types from the
ixgbe_bus_type.  Thanks to Alex Duyck for suggesting this.

Subject: ixgbe: Remove second instance of lan_id variable

This patch removes the redundant lan_id in the phy struct and uses
the bus version.  Both variables exist and intend to represent the
STATUS register LAN_ID field.  However, phy.lan_id is not bit shifted
so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1.
Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and
bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional
lan_id variable and this should make the code less confusing.

Subject: ixgbe: Add support for reporting 2.5G link speed

Now that we can do 2.5G link speed, we need to be able to report it.
Also change the nested triadic involved in creating the log message
to instead use a simpler switch statement to set a string pointer.

Subject: ixgbe: Remove bimodal SR-IOV disabling

When unbinding an SR-IOV device with VFs configured from ixgbe, the
driver behaves in one of two ways.  If max_vfs was specified, the
SR-IOV state is disabled, removing the VFs.  The occurs regardless of
whether the VF count was later modified through sysfs.  If however
max_vfs is zero, such as by not specifying the module parameter, the
VFs persist after the PF is unbound from ixgbe.  If the PF is then
bound to vfio-pci to be assigned to a VM, the PF is non-functional.

>From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV
sysfs callback operation") clearly intended this alternate behavior,
but probably didn't realize the PF doesn't work in this mode.

This bimodal behavior is confusing to users and results in a state
where the PF is broken for other uses unless the user sets
sriov_numvfs to zero prior to unbinding the device.  Remove this
behavior so that VFs are removed and the PF is functional for other
uses after unbind, regardless of the way VFs are enabled.

Commit a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.")
added a new argument to fixed_phy_register(), but missed to update bgmac
driver, causing the following build failure:

drivers/net/ethernet/broadcom/bgmac.c:1450:2: error: too few arguments to function 'fixed_phy_register'

Add the missing argument.

Subject: xen-netback: add support for multicast control

Xen's PV network protocol includes messages to add/remove ethernet
multicast addresses to/from a filter list in the backend. This allows
the frontend to request the backend only forward multicast packets
which are of interest thus preventing unnecessary noise on the shared
ring.

The canonical netif header in git://xenbits.xen.org/xen.git specifies
the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal
necessary changes have been pulled into include/xen/interface/io/netif.h.

To prevent the frontend from extending the multicast filter list
arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries.
This limit is not specified by the protocol and so may change in future.
If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD
sent by the frontend will be failed with NETIF_RSP_ERROR.

Subject: net: fec: clear receive interrupts before processing a packet

The patch just to re-submit the patch "db3421c114cfa6326" because the
patch "4d494cdc92b3b9a0" remove the change.

Clear any pending receive interrupt before we process a pending packet.
This helps to avoid any spurious interrupts being raised after we have
fully cleaned the receive ring, while still allowing an interrupt to be
raised if we receive another packet.

The position of this is critical: we must do this prior to reading the
next packet status to avoid potentially dropping an interrupt when a
packet is still pending.
