[PATCH v2 04/10] ath11k: MBSSID configuration during vdev create/start

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

 

Configure multiple BSSID flags and index of the transmitting interface
in vdev create/start commands depending on the service bit
WMI_TLV_SERVICE_MBSS_PARAM_IN_VDEV_START_SUPPORT.

Tested-on : IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
