In case of A-MSDUs, the trans layer is taking care of building
the subframes (out of the given skb), according to the given gso_size.
However, in some testing flows, we want to build the whole A-MSDU
frame in a different place (e.g. userspace), and ask the driver
to send it as-is.
In case of gso_size==0, simply treat the frame as normal-frame,
although the A-MSDU flag is set.

However dividing by 256 will make avg_rssi almost the same as

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

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 c18d8f5095 ("rtlwifi:
rtl8723be: Add antenna select module parameter"). There was still a
problem with Bluetooth coexistence, which was addressed with commit
baa1702290 ("rtlwifi: btcoexist: Implement antenna selection").
There were still problems, thus there were commit 0ff78adeef
("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d62269283
("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
