Now that we have a default handler there's no need anymore to list every
unsupported event id anymore, so remove that to clean this up.
While at it remove the pointless todo comment and change the debug message to
follow the preferred style.

Add a debug message for every WMI event to make it easier track what's
happening in WMI. For better readability start every debug message with
"event".

Now that the previous patch changed ath11k_dbg() to print the debug level
there's no need to have the level in the actual message anymore. So remove those.

To make it easier understand the context of a debug message print the debug
level before the actual message. An example:
[21867.231900] ath11k_pci 0000:06:00.0: wmi processed regulatory ext channel list
The tracepoint call is not modified, it's better to userspace print the debug
level if needed.

On EDMA capable hardware, ath9k_txq_list_has_key() can enter infinite
loop if it is called while all txq_fifos have packets that use different
key that the one we are looking for. Fix it by exiting the loop if all
txq_fifos have been checked already.
Because this loop is called under spin_lock_bh() (see ath_txq_lock) it
causes the following rcu stall:

When multiple transmit scheduler queues feed a TL1 transmit link, the
SMQ flush initiated on a low priority queue might get stuck when a high
priority queue fully subscribes the transmit link. This inturn effects
interface teardown. To avoid this, temporarily XOFF all TL1's other
immediate child transmit scheduler queues and also clear any rate limit
configuration on all the scheduler queues in SMQ(flush) hierarchy.

The DWRR MTU config added for SDP and RPM/LBK links on CN10K
silicon is further extended on CK10KB silicon variant and made
it configurable. Now there are 4 DWRR MTU config to choose while
setting transmit scheduler's RR_WEIGHT.
Here we are reserving one config for each of RPM, SDP and LBK.
NIXX_AF_DWRR_MTUX(0) ---> RPM
NIXX_AF_DWRR_MTUX(1) ---> SDP
NIXX_AF_DWRR_MTUX(2) ---> LBK
PF/VF drivers can choose the DWRR_MTU to be used by setting
SMQX_CFG[pkt_link_type] to one of above. TLx_SCHEDULE[RR_WEIGHT]
is to be as configured 'quantum / 2^DWRR_MTUX[MTU]'. DWRR_MTU
of each link is exposed to PF/VF drivers via mailbox for
RR_WEIGHT calculation.

Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS
calculation.
AF consumer may have requirement as we can select only SRC or DST data for
RSS calculation in L3, L4 layers. With this requirement there will be
following combinations, IPV[4,6]_SRC_ONLY, IPV[4,6]_DST_ONLY,
[TCP,UDP,SCTP]_SRC_ONLY, [TCP,UDP,SCTP]_DST_ONLY. So, instead of creating
a bit for each combination, we are using upper 4 bits (31:28) in the
flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC,
30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg,
so that we don't need to change the existing ABI.

The NPC MCAM entries are currently divided into three priority zones
in AF driver: high, mid, and low. The high priority zone and low priority
zone take up 1/8th (each) of the available MCAM entries, and remaining
going to the mid priority zone.
The current allocation scheme may not meet certain requirements, such
as when a requester needs more high priority zone entries than are
reserved. This patch adds a devlink configurable option to increase the
number of high priority zone entries that can be allocated by requester.
The max number of entries that can be reserved for high priority usage
is 100% of available MCAM entries.
Usage:
1) Change high priority zone percentage to 75%:
devlink -p dev param set pci/0002:01:00.0 name npc_mcam_high_zone_percent \
value 75 cmode runtime
2) Read high priority zone percentage:
devlink -p dev param show pci/0002:01:00.0 name npc_mcam_high_zone_percent
The devlink set configuration is only permitted when no MCAM entries
are assigned, i.e., all MCAM entries are free, indicating that no PF/VF
driver is loaded. So user must unload/unbind PF/VF driver/devices before
modifying the high priority zone percentage.

This flaw is detected by smatch:
drivers/net/wireless/realtek/rtw88/mac.c:748 __rtw_download_firmware()
warn: missing unwind goto?
Though most things of dlfw_fail have been done by
download_firmware_end_flow() and wlan_cpu_enable(), an exception is that
download_firmware_end_flow() clear BIT_MCUFWDL_EN bit conditionally.
So, make this change to clear the bit.

Q-USGMII is a derivative of USGMII, that uses a specific formatting for
the control word. The layout is close to the USXGMII control word, but
doesn't support speeds over 1Gbps. Use a dedicated decoding logic for
the USGMII control word, re-using USXGMII definitions but only considering
10/100/1000Mbps speeds

Guarantee that when probe() is run again, PTM and PCI busmaster will be
in the same state as it was if the driver was never loaded.
Avoid an i225/i226 hardware issue that PTM requests can be made even
though PCI bus mastering is not enabled. These unexpected PTM requests
can crash some systems.
So, "force" disable PTM and busmastering before removing the driver,
so they can be re-enabled in the right order during probe(). This is
more like a workaround and should be applicable for i225 and i226, in
any platform.

There could be a race condition during link down where interrupt

TX completion. Properly clear the TX buffer/descriptor ring and
disable the TX Queue ring in igc_free_tx_resources() to avoid that.

mlx5-updates-2023-06-09
1) Embedded CPU Virtual Functions
2) Lightweight local SFs
Daniel Jurgens says:
====================
Embedded CPU Virtual Functions
This series enables the creation of virtual functions on Bluefield (the
embedded CPU platform). Embedded CPU virtual functions (EC VFs). EC VF
creation, deletion and management interfaces are the same as those for
virtual functions in a server with a Connect-X NIC.
When using EC VFs on the ARM the creation of virtual functions on the
host system is still supported. Host VFs eswitch vports occupy a range
of 1..max_vfs, the EC VF vport range is max_vfs+1..max_ec_vfs.
Every function (PF, ECPF, VF, EC VF, and subfunction) has a function ID
associated with it. Prior to this series the function ID and the eswitch
vport were the same. That is no longer the case, the EC VF function ID
range is 1..max_ec_vfs. When querying or setting the capabilities of an
EC VF function an new bit must be set in the query/set HCA cap
structure.
This is a high level overview of the changes made:
- Allocate vports for EC VFs if they are enabled.
- Create representors and devlink ports for the EC VF vports.
- When querying/setting HCA caps by vport break the assumption
that function ID is the same a vport number and adjust
accordingly.
- Create a new type of page, so that when SRIOV on the ARM is
disabled, but remains enabled on the host, the driver can
wait for the correct pages.
- Update SRIOV code to support EC VF creation/deletion.
===================
Lightweight local SFs:
Last 3 patches form Shay Drory:
SFs are heavy weight and by default they come with the full package of
ConnectX features. Usually users want specialized SFs for one specific
purpose and using devlink users will almost always override the set of
advertises features of an SF and reload it.
Shay Drory says:
================
In order to avoid the wasted time and resources on the reload, local SFs
will probe without any auxiliary sub-device, so that the SFs can be
configured prior to its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

After the struct mlxsw_sp_netevent_work.n field initialization is moved
here, the body of code that handles NETEVENT_NEIGH_UPDATE is almost
identical to the one in the helper function. Therefore defer to the helper
instead of inlining the equivalent.
Note that previously, the code took and put a reference of the netdevice.
The new code defers to mlxsw_sp_dev_lower_is_port() to obviate the need for
taking the reference.

This code handles NETEVENT_DELAY_PROBE_TIME_UPDATE, which is invoked every
time the delay_probe_time changes. mlxsw router currently only maintains
one timer, so the last delay_probe_time set wins.
Currently, mlxsw uses mlxsw_sp_port_lower_dev_hold() to find a reference to
the router. This is no longer necessary. But as a side effect, this makes
sure that only updates to "interesting netdevices" (ones that have a
physical netdevice lower) are projected.
Retain that side effect by calling mlxsw_sp_port_dev_lower_find_rcu() and
punting if there is none. Then just proceed using the router pointer that's
already at hand in the helper.
Note that previously, the code took and put a reference of the netdevice.
Because the mlxsw_sp pointer is now obtained from the notifier block, the
port pointer (non-) NULL-ness is all that's relevant, and the reference
does not need to be taken anymore.

Currently, the window_drop stats persist even if an incorrect Qdisc was
removed from the interface and a new one is installed. This is because
the enetc driver keeps the state, and that is persistent across multiple
Qdiscs.
To resolve the issue, clear all win_drop counters from all TX queues
when the currently active Qdisc is removed. These counters are zero
by default. The counters visible in ethtool -S are also affected,
but I don't care very much about preserving those enough to keep them
monotonically incrementing.

The taprio Qdisc creates child classes per netdev TX queue, but
taprio_dump_class_stats() currently reports offload statistics per

dequeue priority, so this is incorrect and we shouldn't be bundling up
the TXQ stats when reporting them, as we currently do in enetc.

stats and not TC offload stats.

The commit 59a0b022aa24 ("ipvlan: Make skb->skb_iif track skb->dev for l3s

works for IPv4, as in raw_v4_input() the dif is from inet_iif(skb), which
is skb->skb_iif when there is no route.
But for IPv6, the fix is not enough, because in ipv6_raw_deliver() ->
raw_v6_match(), the dif is inet6_iif(skb), which is returns IP6CB(skb)->iif
instead of skb->skb_iif if it's not a l3_slave. To fix the IPv6 part
issue. Let's set IP6CB(skb)->iif to correct ifindex.
BTW, ipvlan handles NS/NA specifically. Since it works fine, I will not
reset IP6CB(skb)->iif when addr->atype is IPVL_ICMPV6.

Tony Nguyen says:
====================
ice: Improve miscellaneous interrupt code
Jacob Keller says:
This series improves the driver's use of the threaded IRQ and the
communication between ice_misc_intr() and the ice_misc_intr_thread_fn()
which was previously introduced by commit 1229b33973c7 ("ice: Add low
latency Tx timestamp read").
First, a new custom enumerated return value is used instead of a boolean for
ice_ptp_process_ts(). This significantly reduces the cognitive burden when
reviewing the logic for this function, as the expected action is clear from
the return value name.
Second, the unconditional loop in ice_misc_intr_thread_fn() is removed,
replacing it with a write to the Other Interrupt Cause register. This causes
the MAC to trigger the Tx timestamp interrupt again. This makes it possible
to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond
just the Tx timestamps. It is also easier to reason about since the thread
function will exit cleanly if we do something like disable the interrupt and
call synchronize_irq().
Third, refactor the handling for external timestamp events to use the
miscellaneous thread function. This resolves an issue with the external
time stamps getting blocked while processing the periodic work function
task.
Fourth, a simplification of the ice_misc_intr() function to always return
IRQ_WAKE_THREAD, and schedule the ice service task in the
ice_misc_intr_thread_fn() instead.
Finally, the Other Interrupt Cause is kept disabled over the thread function
processing, rather than immediately re-enabled.
Special thanks to Michal Schmidt for the careful review of the series and
pointing out my misunderstandings of the kernel IRQ code. It has been
determined that the race outlined as being fixed in previous series was
actually introduced by this series itself, which I've since corrected.

Adds runtime pm support for 7560.
As part of probe procedure auto suspend is enabled and auto suspend
delay is set to 5000 ms for runtime pm use. Later auto flag is set
to power manage the device at run time.
On successful communication establishment between host and device the
device usage counter is dropped and request to put the device into
sleep state (suspend).
In TX path, the device usage counter is raised and device is moved out
of sleep(resume) for data transmission. In RX path, if the device has
some data to be sent it request host platform to change the power state
by giving PCI PME message.

The cited commit aimed to ensure that Virtual Functions (VFs) assign a
queue affinity to a Queue Pair (QP) to distribute traffic when
the LAG master creates a hardware LAG. If the affinity was set while
the hardware was not in LAG, the firmware would ignore the affinity value.
However, this commit unintentionally assigned an affinity to QPs on the LAG
master's VPORT even if the RDMA device was not marked as LAG-enabled.
In most cases, this was not an issue because when the hardware entered
hardware LAG configuration, the RDMA device of the LAG master would be
destroyed and a new one would be created, marked as LAG-enabled.
The problem arises when a user configures Equal-Cost Multipath (ECMP).
In ECMP mode, traffic can be directed to different physical ports based on
the queue affinity, which is intended for use by VPORTS other than the
E-Switch manager. ECMP mode is supported only if both E-Switch managers are
in switchdev mode and the appropriate route is configured via IP. In this
configuration, the RDMA device is not destroyed, and we retain the RDMA
device that is not marked as LAG-enabled.
To ensure correct behavior, Send Queues (SQs) opened by the E-Switch
manager through verbs should be assigned strict affinity. This means they
will only be able to communicate through the native physical port
associated with the E-Switch manager. This will prevent the firmware from
assigning affinity and will not allow the SQs to be remapped in case of
failover.

In the last step of the EEH recovery process, the EEH driver calls into
bnx2x_io_resume() to re-initialize the NIC hardware via the function
bnx2x_nic_load(). If an error occurs during bnx2x_nic_load(), OS and
hardware resources are released and an error code is returned to the
caller. When called from bnx2x_io_resume(), the return code is ignored
and the network interface is brought up unconditionally. Later attempts
to send a packet via this interface result in a page fault due to a null
pointer reference.
This patch checks the return code of bnx2x_nic_load(), prints an error
message if necessary, and does not enable the interface.

Create software objects to manage the metadata for encap actions that
can be attached to TC rules. However, since we don't yet have the
neighbouring information (needed to generate the Ethernet header),
all rules with encap actions are marked as "unready" and thus insert
the fallback action into hardware rather than actually offloading the
encapsulation action.
