Subject: [PATCH] ath11k: add software monitor ring descriptor for full monitor
Git-commit: 88ee00d130f744854cdd91ad76a888d9e66996d1
Patch-mainline: v5.17-rc1
References: bsc#1206451
In full monitor mode, monitor destination ring is read in
software monitor ring descriptor format instead of
reo_entrance_ring format. Add new sw_mon_ring descriptor.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01734-QCAHKSWPL_SILICONZ-1
