- Subject: [PATCH] wifi: ath11k: fix monitor vdev creation with firmware
- recovery
- During firmware recovery, the monitor interface is not
- getting created in the driver and firmware since
- the respective flags are not updated properly.
- So after firmware recovery is successful, when monitor
- interface is brought down manually, firmware assertion
- is observed, since we are trying to bring down the
- interface which is not yet created in the firmware.
- Fix this by updating the monitor flags properly per
- phy#, during firmware recovery.
- Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
