From: Muna Sinada Date: Wed, 5 Oct 2022 14:54:45 -0700 Subject: [PATCH] wifi: mac80211: Add VHT MU-MIMO related flags in ieee80211_bss_conf Adding flags for SU Beamformer, SU Beamformee, MU Beamformer and MU Beamformee for VHT. This is utilized to pass MU-MIMO configurations from user space to driver in AP mode.
