Subject: [PATCH] mac80211: Add HE MU-MIMO related flags in ieee80211_bss_conf
Date:   Tue, 7 Jun 2022 10:54:00 -0700
Message-ID: <1654624440-30386-1-git-send-email-quic_msinada@quicinc.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Adding flags for SU Beamformer, SU Beamformee, MU Beamformer and Full
Bandwidth UL MU-MIMO for HE. This is utilized to pass MU-MIMO
configurations from user space to driver.
