Despite never getting called from atomic context,
dma_tx_fragment() calls alloc_skb() with GFP_ATOMIC,

GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,

In case of "any" wowlan trigger is configured, no valid wakeup filter

Moreover, the fw assumes there's no connection when there are no configured

This leads to the station info not being updated on D3 command, causing
rate_n_flags to be 0 when the offloading code sends tx frame (triggering
SYSASSERT_102C due to invalid antenna param)
Note: "any" trigger is currently assumed to only be used when entering

mt76: rework tx power handling
There were a number of issues in the existing tx power handling code:
1. The EEPROM target power for chain 0 refers to the actual output power
after the channel and bandwidth delta have been added to the initial
channel gain. This means the delta values should not be added/subtracted
for the rate power calculation
2. When power is reduced significantly, the initial channel gain
underflows very quickly, while the per-rate power offsets are high.
This miscalculation causes effective tx power to be increased when it
should actually be lowered.
Fix this by trying to adjust the channel gain to the lowest power from
the rate table. In case of under- or overflow, compensate by adding an
appropriate delta to the rate power values.
This makes power configuration more accurate on a wider range of
configurable values

rtlwifi: cleanup 8723be ant_sel definition
Some HP laptops have only a single wifi antenna. This would not be a
problem except that they were shipped with an incorrectly encoded
EFUSE. It should have been possible to open the computer and transfer
the antenna connection to the other terminal except that such action
might void the warranty, and moving the antenna broke the Windows
driver. The fix was to add a module option that would override the
EFUSE encoding. That was done with commit
c18d8f509571 ("rtlwifi:
rtl8723be: Add antenna select module parameter"). There was still a
problem with Bluetooth coexistence, which was addressed with commit
baa170229095 ("rtlwifi: btcoexist: Implement antenna selection").
There were still problems, thus there were commit
0ff78adeef11
("rtlwifi: rtl8723be: fix ant_sel code") and commit
6d6226928369
("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these
attempts at fixing the problem, the code is not yet right. A proper
fix is important as there are now instances of laptops having
RTL8723DE chips with the same problem.
The module parameter ant_sel is used to control antenna number and path.
At present enum ANT_{X2,X1} is used to define the antenna number, but
this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX}
to make it more readable. This change showed examples where incorrect
values were used. It was also possible to remove a workaround in
halbtcoutsrc.c.
The experimental results with single antenna connected to specific path
are now as follows:
ant_sel ANT_MAIN(#1) ANT_AUX(#2)
0 -8 -62
1 -62 -10
2 -6 -60

The firmware message to delete BSS keys expects a BSS index to be passed.
This field is currently hard-coded to 0. Fix this by passing in the index

The encryption type in that message also needs to be set to what was used
when the key was set, so the assignment of vif_priv->encrypt_type is now
done after the firmware command was sent. This reportedly fixes the
following error in AP mode:
wcn36xx: ERROR hal_remove_bsskey response failed err=6
Also, AFAIU, when a BSS is deleted, the firmware apparently drops all the
keys associated with it. Trying to remove the key explicitly afterwards
will hence lead to the following message:
