   4 Subject: [PATCH] wifi: ath11k: fix monitor vdev creation with firmware
   5  recovery
   6
   7 During firmware recovery, the monitor interface is not
   8 getting created in the driver and firmware since
   9 the respective flags are not updated properly.
  10
  11 So after firmware recovery is successful, when monitor
  12 interface is brought down manually, firmware assertion
  13 is observed, since we are trying to bring down the
  14 interface which is not yet created in the firmware.
  15
  16 Fix this by updating the monitor flags properly per
  17 phy#, during firmware recovery.
