Change details:
- When bnad_setup_tx() returns NULL, the error is NOT returned to the caller.
The caller will incorrectly assume success. So Return ENOMEM when bna_tx_create()
fails.
- If bnad_tx_msix_register() fails, call bna_tx_destroy() to free tx & to NULL
the bnad reference to tcb.

Currently we already check to see whether the BNAD_TXQ_TX_STARTED cleared.
But if the tcb structure which contains this flag is also already freed by that
time, we would dereference the NULL pointer. This patch is to check tcb for NULL
pointer, before dereferencing it.

The CT2 HW supports multi-buffer Rx. This patch provides the necessary changes
for bnad to use multi-buffer Rx feature. For BNAD, multi-buffer Rx is by
default enabled when MTU is > 4096. For >4096 MTU, q0 data/large buffers are of
2048 size. As the resource requirements of multi-buffer Rx are different new Rx
needs to be created to use this feature. ASIC posts multiple completions if
frame exceeds buffer size. The last completion is marked with EOP flag.
- Separate HQ and DQ enums for resource allocations and configurations.
- rx_config and rxq structure changes to pass the correct info from bnad.
- DQ depth need not be same as HQ depth. So CQ depth is adjusted accordingly.
- Rx CFG frame size is taken from configured MTU.
- Rx q0 buffer size is configured from bnad s rx_config when multi-buffer is
enabled.
- Poll for entire frame completion.
- Once EOP completion is received gather the number of vectors used by the
frame to submit it to the stack.
- Changed MTU to frame size wherever necessary.

Change Details:
- Added bna_rx_ucast_listset() for synchronous ucast listadd operation.
- Clear mac->handle before adding it to free_q.
- bnad_set_rx_mode() rewritten. bnad_set_rx_mode() adds the MACs in uc_list
to UCAM. If it exceeds the max supported, DEFAULT mode is turned on. If
MCAM limit is exceeded, ALLMULTI mode is turned on.
- Clear CF flags, check for the new mode and reprogram the Rx approach.
- Added bnad_set_rx_ucast_fltr() and bnad_set_rx_mcast_fltr().
- Check for IFF_PROMISC to set the correct mode.

Change Details:
- bna_rx_mcast_listset() API first looks at free_q only and not at other
pending Qs rendering it non-deterministic of giving an upper limit.
Modify bna_rx_mcast_listset() implementation to not use only half of the
limit.
- Allocate and initialize queue for deleting
- Segregate the adding and deleting process by using separate queues.
- The filter framework in bna does not let adding addresses to its max capacity
due to asynchronous operations involved.
Provide a synchronous option to set a given list.

Use print_hex_dump() instead to hex dump and remove the print buffer

weren't freed upon exit. Therefore, add a small helper function that
walks label tables and frees them. Since also NULL can be passed to

net: Add rxhash utility hash functions
v3:
There's really nothing specific about rxhash that constrains
it to be a value just for these receive path. Drop the 'rx'
part in utility functions, including skb_get_rxhash. In subsequent
patches, we can change the rxhash and l4_rxhash names also, as
well as abstracting out the interface to the hash.
Added comments about hash types per feedback.
In this version I'm omitting the changes to drivers to make the
patch set manageable. Will add those changes in followup pathes.
-----
This patch series introduce skb_set_rxhash and skb_clear_rxhash
which are called to set the rxhash (from network drivers) and
to clear the rxhash. This API should be used instead of updating
fields in the skbuff directly.

In several places 'skb->rxhash = 0' is being done to clear the
rxhash value in an skb. This does not clear l4_rxhash which could
still be set so that the rxhash wouldn't be recalculated on subsequent
call to skb_get_rxhash. This patch adds an explict function to clear
all the rxhash related information in the skb properly.
skb_clear_hash_if_not_l4 clears the rxhash only if it is not marked as
l4_rxhash.
Fixed up places where 'skb->rxhash = 0' was being called.

While investigating performance problems on small RPC workloads,
I noticed linux TCP stack was always splitting the last TSO skb
into two parts (skbs). One being a multiple of MSS, and a small one
with the Push flag. This split is done even if TCP_NODELAY is set,
or if no small packet is in flight.
Example with request/response of 4K/4K
IP A > B: . ack 68432 win 2783 <nop,nop,timestamp 6524593 6525001>
IP A > B: . 65537:68433(2896) ack 69632 win 2783 <nop,nop,timestamp 6524593 6525001>
IP A > B: P 68433:69633(1200) ack 69632 win 2783 <nop,nop,timestamp 6524593 6525001>
IP B > A: . ack 68433 win 2768 <nop,nop,timestamp 6525001 6524593>
IP B > A: . 69632:72528(2896) ack 69633 win 2768 <nop,nop,timestamp 6525001 6524593>
IP B > A: P 72528:73728(1200) ack 69633 win 2768 <nop,nop,timestamp 6525001 6524593>
IP A > B: . ack 72528 win 2783 <nop,nop,timestamp 6524593 6525001>
IP A > B: . 69633:72529(2896) ack 73728 win 2783 <nop,nop,timestamp 6524593 6525001>
IP A > B: P 72529:73729(1200) ack 73728 win 2783 <nop,nop,timestamp 6524593 6525001>
We can avoid this split by including the Nagle tests at the right place.
Note : If some NIC had trouble sending TSO packets with a partial
last segment, we would have hit the problem in GRO/forwarding workload already.
tcp_minshall_update() is moved to tcp_output.c and is updated as we might
feed a TSO packet with a partial last segment.
This patch tremendously improves performance, as the traffic now looks
like :
IP A > B: . ack 98304 win 2783 <nop,nop,timestamp 6834277 6834685>
IP A > B: P 94209:98305(4096) ack 98304 win 2783 <nop,nop,timestamp 6834277 6834685>
IP B > A: . ack 98305 win 2768 <nop,nop,timestamp 6834686 6834277>
IP B > A: P 98304:102400(4096) ack 98305 win 2768 <nop,nop,timestamp 6834686 6834277>

John W. Linville says:
====================
Please pull this batch of updates for the 3.14 stream...
For the Bluetooth bits, Gustavo says:
"This is the first batch of patches intended for 3.14. There is
nothing big here. Most of the code are refactors, clean up, small
fixes, plus some new device id support."
And...
"More patches to 3.14. Here we have the support for Low Energy
Connection Oriented Channels (LE CoC). Basically, as the name says,
this adds supports for connection oriented channels in the same way
we already have them for BR/EDR connections so profiles/protocols
that work on top of BR/EDR can now work on LE plus a plenty of new
possibilities for LE."
For the ath10k bits, Kalle says:
"Janusz and Marek implemented DFS support to ath10k, but the code is
not enabled yet due to missing cfg80211/mac80211 patches (it will be
enabled in the next pull request). Michal did some device reset fixes
and made it possible for ath10k to share an interrupt with another
device. And lots of smaller fixes from different people."
For the iwlwifi bits, Emmanuel says:
"I have here a big rework of the rate control by Eyal. This is obviously
the biggest part of this batch.
I also have enhancement of protection flags by Avri and a few bits for
WoWLAN by Eliad and Luca. Johannes cleans up the debugfs plus a few
fixes. I provided a few things for Bluetooth coexistence.
Besides this we have an implementation for low priority scan."
Along with all that, there are big batches of updates to mwifiex and
ath9k, Jeff Kirsher's FSF address fix patches, and a handful of other
bits here and there.
Please let me know if there are problems!

net: phy: Ethernet PHY powerdown optimization
This is v2 of the ethernet PHY power optimization patches to reduce
power consumption of network PHYs with link that are either unused or
the corresponding netdev is down.
Compared to the last version, this patch set drops a patch to disable
unused PHYs after late initcall, as it is not compatible with a modular
mdio bus [1]. I'll investigate different ways to have a modular mdio bus
driver get notified when driver loading is done.

When phydev is going to HALTED state, we can try to suspend it to
safe more power. phy_suspend helper will check if PHY can be suspended,
so just call it when entering HALTED state.

This adds helper functions to resume and suspend a given phy_device
by calling the corresponding driver callbacks if available.

Marvell PHYs support generic PHY suspend/resume, so provide those
callbacks to all marvell specific drivers.

When using phydev, it should be phy_start/phy_stop'ed properly. This
driver doesn't do that, so add the corresponding calls to port_start/
stop respectively.

Members of 'struct association' are not in appropriate order to
reuse compiler added padding on 64bit architectures. In this patch
we reorder those struct members and help reduce the size of the
structure from 2776 bytes to 2720 bytes on 64 bit architectures.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to i40e only (again).
Jesse provides a fix for when tx_rings structure is NULL and we do not want
to panic. Then refactors the flow control set up and disables L2 flow control
by default. Provides some trivial fixes as well as prevent compiler warnings.
Then to align to similar behaviour in ixgbe, use the total number of CPUs in
the system to suggest the number of transmit and receive queue pairs.
Shannon provides a i40e ethtool fix to get some more reasonable information
reports back out to the ethtool. In addition, fixes PF reset after offline
test, where it reorders the test to put the register test last as it is the
only one that needs a reset, and we wait to trigger the reset until after we
clear the testing bit. Lastly provides basic support for handling suspend
and resume for now, later on Wake-On-LAN support will be added.
Anjali provides changes to tell the stack about our actual number of queues
in order for RFS/RPS/XFS to work correctly. Then provides several patches to
implement dynamically changing the queue count for the main VSI. Adds
basic support for get/set channels for RSS so that the number of receive and
transmit queue pair can be changed via ethtool. Cleans up the use of
rtnl_lock in the reset patch since it runs from a work time.
Neerav Parikh cleans up the VF interface to remove FCoE code as this
feature will not be supported on VF interfaces.
v2:
- submitted patch 1 to net (since it was a fix needed for net), so dropped
from this series (this patch will get added to net-next when Dave syncs
his trees)
- Dropped patches 4 & 11 from previous submission because of feedback
received from Ben Hutchings and Sergei Shtylyov.
