Felix Fietkau 168c6f89a2 ath9k_hw: use a software timer for btcoex no_stomp_timer
TSF accuracy is not needed here, and there is only one usable generic
timer that is supported by all chips and uses the primary TSF counter.

Bing Zhao 82efa16ad2 mwifiex: download per country tx power table to firmware
When driver gets regulatory domain change notifications or before
associates to an AP with Country IE, the txpwrlimit table stored
in device tree for that country is downloaded to firmware.

The txpwrlimit downloading will happen only at the first time
when the alpha2 country code is changed. World regulatory domain
"00" notification doesn't trigger the downloading. This behavior
is same as domain_info command.

Arend van Spriel 36c4e7e4aa brcmfmac: clarify struct brcmf_sdio_dev::func[0] reference
The struct brcmf_sdio_dev contains array of sdio functions that
are used in the driver. However, during probe func[0] entry was
assigned to the function 1 reference. This was corrected upon
doing the actual I/O access. This patch makes it more clear by
creating the func[0] entry properly and use it as is during
I/O access.

Hante Meuleman 7b8a466e7c brcmfmac: Combine protocol push hdr and bus txdata.
For the transmission of data a protocol push hdr is performed
followed by a bus txdata call. For the new protocol msgbuf this
is not workable. Since they are already "loosely" coupled for
bcdc protocol they are combined. This means that txdata will
go "through" the protocol layer and a seperate protocol push
hdr will not be needed anymore.

Eyal Shapira 4107dbd277 iwlwifi: mvm: rs: remove unnecessary debug logs
The logs are emitted in a flow in which there were retries
and the rates in the rate table entry didn't match the active
or search table. This doesn't indicate a problem and is
expected in most cases where there will be retries for some
reason. Remove the logs.

Eyal Shapira e07be6d3fe iwlwifi: mvm: rs: improve rates table algo
The new logic will attempt more rates with less retries
per rate. Also when starting off with MIMO it will
fallback to SISO with the same MCS and only then to Legacy.
Previously we fell back directly to Legacy.

Eyal Shapira ca6f38ff4b iwlwifi: mvm: rs: avoid recalc of supported legacy rate mask
The supported legacy rate mask is initialized when rs
is initialized based on the remote peer supported rates.
There's no need to re mask it repeatedly with the supported
remote peer rates.

Eyal Shapira 8fc7c58c03 iwlwifi: mvm: rs: refactor building the LQ command
Simplify the code a bit more by extracting the rates table
building logic into a separate function and handle setting
a fixed rate for debug in a separate flow.
Also avoid using and saving ucode rate format in different
places. Instead use rs_rate struct and convert to ucode format
only when filling the rates table in the LQ command.

Current firmware doesn't handle well uAPSD in P2P Client.
When it will be fixed, the firmware will set a TLV flag to notify
the driver that uAPSD is supported in P2P client mode.
Check this flag when sending power command for P2P client.

Arik Nemtsov 2a988e9808 iwlwifi: trans: prevent reprobe on repeated FW errors before restart
In case a sync command timeouts or Tx is stuck while a FW error
interrupt arrives, we might call iwl_op_mode_nic_error twice before
a restart has been initiated. This will cause a reprobe. Unify calls
to this function at the transport level and only call it on the first
FW error in a given by checking the transport FW error flag.

While at it, remove the privately defined iwl_nic_error from PCIE code
and use the common callback instead.
