| 3 | Subject: [PATCH] wifi: mac80211: Add HE MU-MIMO related flags in |
| 4 | ieee80211_bss_conf |
| 5 | |
| 6 | Adding flags for SU Beamformer, SU Beamformee, MU Beamformer and Full |
| 7 | Bandwidth UL MU-MIMO for HE. This is utilized to pass MU-MIMO |
| 8 | configurations from user space to driver in AP mode. |
