Subject: [PATCH] wifi: ath11k: fix Tx power value during active CAC
|
|
|
|
Tx power is fetched from firmware's pdev stats. However, during active
|
|
CAC, firmware does not fill the current Tx power and sends the max
|
|
initialised value filled during firmware init. If host sends this power
|
|
to user space, this is wrong since in certain situations, the Tx power
|
|
could be greater than the max allowed by the regulatory. Hence, host
|
|
should not be fetching the Tx power during an active CAC.
|
|
|
|
Fix this issue by returning -EAGAIN error so that user space knows that there's
|
|
no valid value available.
|
|
|
|
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
