Subject: [PATCH] ath11k: send proper txpower and maxregpower values to
|
|
firmware
|
|
|
|
Set proper values for max_regpower, max_power, max_antenna_gain as it
|
|
is because firmware will convert power values to 0.5dbm steps by
|
|
multiplying it with 2.
|
|
|
|
If txpower is not set, it will lead to cca stuck resulting in latency
|
|
issues for QCN9074.
|
|
|
|
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01386-QCAHKSWPL_SILICONZ-1
