Subject: ath10k: fix max antenna gain unit
|
|
||||||
|
|
||||||
Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
|
|
||||||
steps). This isn't the case for max_antenna_gain - which is still expected
|
|
||||||
by the firmware as dB.
|
|
||||||
|
|
||||||
The firmware is converting it from dB to the internal (twicepower)
|
|
||||||
representation when it calculates the limits of a channel. This can be seen
|
|
||||||
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
|
|
||||||
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).
|
|
||||||
|
|
||||||
Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.
|
|
||||||
