e5c95ca094 mac80211: Improve confusing comment around tx_info clearing 
The comment above the ieee80211_tx_info_clear_status() helper was somewhat
confusing as to which fields it was or wasn't clearing. So replace it by
something that is hopefully more, well, clear.

bd917b3d28 rtl8xxxu: fill up txrate info for gen1 chips 
RTL8188CUS/RTL8192CU(gen1) don't support rate adaptive report hence
no real txrate info can be retrieved. The vendor driver reports the
highest rate in HT capabilities from the IEs to avoid empty txrate.
This commit initiates the txrate information with the highest supported
rate negotiated with AP. The gen2 chip keeps update the txrate from
the rate adaptive reports, and gen1 chips at least have non-NULL txrate
after associated.

a0ff2a8719 rtlwifi: replace usage of found with dedicated list iterator variable 
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

92cadedd9d brcmfmac: Avoid keeping power to SDIO card unless WOWL is used 
Keeping the power to the SDIO card during system wide suspend, consumes
energy. Especially on battery driven embedded systems, this can be a
problem. Therefore, let's change the behaviour into allowing the SDIO card
to be powered off, unless WOWL is supported and enabled.

Note that, the downside from this change, is that during system resume the
SDIO card needs to be re-initialized and the FW must be re-programmed. Even
if this may take some time to complete, it should we worth it, rather than
draining the battery.

3e12968f6d mwifiex: add mutex lock for call in mwifiex_dfs_chan_sw_work_queue 
cfg80211_ch_switch_notify uses ASSERT_WDEV_LOCK to assert that
net_device->ieee80211_ptr->mtx (which is the same as priv->wdev.mtx)
is held during the function's execution.
mwifiex_dfs_chan_sw_work_queue is one of its callers, which does not
hold that lock, therefore violating the assertion.
Add a lock around the call.

Disclaimer:
I am currently working on a static analyser to detect missing locks.
This was a reported case. I manually verified the report by looking
at the code, so that I do not send wrong information or patches.
After concluding that this seems to be a true positive, I created
this patch.
However, as I do not in fact have this particular hardware,
I was unable to test it.

f59acdde51 rtw89: support variant of fill_txdesc 
The txdesc is descriptor related to skb->data. The v1 version contains
8 dwords txwd_body and 6 dwords txwd_info, and the format is also different
from original one.

6d5b5d6290 rtw89: pci: support variant of fill_txaddr_info 
The txaddr_info is used to fill the DMA address of skb->data. The v1
version can support up to 10 entries, but the maximum size of each entry
is 2047, so it fill more than one entry for large packet, like 3000 bytes.

to allocate different header size and fill content by fill_txdesc_fwcmd.

edb896297a rtw89: support FW crash simulation 
Originally, there is already a mechanism, SER (system error recover),
to deal with HW/FW recovery. After FW v0.13.36.0, FW supports a H2C
(host to chip) command to make a CPU exception. Then, SER is supposed
to catch this FW crash and do L2 reset. This feature is a simulation
to verify if flow of recovering from FW crash works.

Usage of fw_crash debugfs is as the following.
$ echo 1 > fw_crash	// trigger FW crash and wait SER handling
$ cat fw_crash		// return 0 if restart has been done
