ath.git patches for v5.18. Major changes:

ath11k

* add LDPC FEC type in 802.11 radiotap header

* enable RX PPDU stats in monitor co-exist mode

wcn36xx

* implement survey reporting

For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new
alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to
firmware for all chips currently. When test with WCN6855/QCA6390 chips,
this WMI CMD leads firmware crash.

For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used
to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to
use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID.

Add flag current_cc_support in hardware parameters, it is used to
distinguish AP/STA platform. After that, the firmware will work
normal and the regulatory feature works well for QCA6390/WCN6855.

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
field initialization.

In htc_connect_service() svc_meta_len and pad are not initialized. Based
on code it looks like in current skb there is no service data, so simply
initialize svc_meta_len to 0.

htc_issue_send() does not initialize htc_frame_hdr::control array. Based
on firmware code, it will initialize it by itself, so simply zero whole
array to make KMSAN happy

udp/ipv6 optimisations

Shed some weight from udp/ipv6. Zerocopy benchmarks over dummy showed
~5% tx/s improvement, should be similar for small payload non-zc
cases.

The performance comes from killing 4 atomics and a couple of big struct
memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for
cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10
kill extra 88B memset and memcpy respectively.

In Spectrum-2 and later ASICs, each TCAM region has a default action
that is executed in case a packet did not match any rule in the region.
The location of the action in the database (KVDL) is computed by adding
the region's index to a base value.

Some TCAM regions are not exposed to the host and used internally by the
device. Allocate KVDL entries for the default actions of these regions
to avoid the host from overwriting them.

With mlxsw, lookups in the internal regions are not currently performed,
but it is a good practice not to overwrite their default actions.

When processing events generated by the device's firmware, the driver
protects itself from events reported for non-existent local ports, but
not for the CPU port (local port 0), which exists, but does not have all
the fields as any local port.

This can result in a NULL pointer dereference when trying access
'struct mlxsw_sp_port' fields which are not initialized for CPU port.

Commit 63b08b1f ("mlxsw: spectrum: Protect driver from buggy firmware")
already handled such issue by bailing early when processing a PUDE event
reported for the CPU port.

Generalize the approach by moving the check to a common function and
making use of it in all relevant places.

mlx5-updates-2022-01-27

1) Dima, adds an internal mlx5 steering callback per steering provider
   (FW vs SW steering), to advertise steering capabilities implemented by
   each module, this helps upper modules in mlx5 to know what is
   supported and what's not without the need to tell what is the underlying
   steering mode.
   2nd patch is the usecase where this interface is used to implement
   Vlan Push/pop for uplink with SW steering, where in FW mode it's not
   supported yet.

2) Roi Dayan improves code readability and maintainability
   as preparation step for multi attribute instance per flow
   in mlx5 TC module

   Currently the mlx5_flow object contains a single mlx5_attr instance.
   However, multi table actions (e.g. CT) instantiate multiple attr instances.

   This is a refactoring series in a preparation to support multiple
   attribute instances per flow.
   The commits prepare functions to get attr instance instead of using
   flow->attr and also using attr->flags if the flag is more relevant
   to be attr flag and not a flow flag considering there will be multiple
   attr instances. i.e. CT and SAMPLE flags.

Some older NIC hardware isn't capable of doing VLAN push on RX and pop

A workaround has been added in software to support it, but it has a
performance penalty since it requires a hairpin + loopback.

There's no such limitation with the newer NICs, so no need to pay the
price of the w/a. With this change the software w/a is disabled for

There are two different internal steering modes, abstracted from the
rest of the driver. In order to keep upper layer of the driver agnostic
to the differences in capabilities of the steering modes, this patch
introduces mlx5_fs_get_capabilities() API to check if a certain software
defined capability is supported. It differs from the capabilities
exposed by the hardware, as it takes into account the flow steering mode
(SMFS/DMFS) currently enabled.

This implementation supports only two capability flags:

  MLX5_FLOW_STEERING_CAP_VLAN_PUSH_ON_RX
  MLX5_FLOW_STEERING_CAP_VLAN_POP_ON_TX

They map to DR_ACTION_STATE_PUSH_VLAN and DR_ACTION_STATE_POP_VLAN
actions, implemented in SW steering earlier in commit f5e22be5
("net/mlx5: DR, Split modify VLAN state to separate pop/push states").
Which enables using of pop/push vlan without restrictions, e.g. doing
vlan pop on TX and RX, compared to FW steering that supports only vlan
pop on RX and push on TX.

Other capabilities can be added in the future.

The flags are flow attrs and not esw specific attr flags.
Refactor to remove the esw prefix and move from eswitch.h
to en_tc.h where struct mlx5_flow_attr exists.

ct clear action is a normal flow with a modify header for registers to
0. there is no need for any special handling in tc_ct.c.
Parsing of ct clear action still allocates mod acts to set 0 on the
registers and the driver continue to add a normal rule with modify hdr
context.

In later commit we are going to instantiate multiple attr instances
for flow instead of single attr.
Parsing TC sample allocates a new memory but there is no symmetric
cleanup in the infrastructure.
To avoid asymmetric alloc/free use sample_attr as part of the flow attr
and not allocated and held as a pointer.
This will avoid a cleanup leak when sample action is not on the first
attr.

The driver doesn't support multiple CT actions.
Multiple CT clear actions are ok as they are redundant also with
another CT actions.

Make sure mlx5e_tc_add_flow_mod_hdr() use the correct attr and not flow->attr.
