[PATCH 02/14] wifi: ath12k: Enable filter config for monitor destination ring

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add provision to configure monitor filter for the destination
ring. These filters are used for requesting statistics or monitor mode
through the monitor destination ring.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
