Subject: [PATCH] wifi: mac80211: Add HE MU-MIMO related flags in
|
|
|
|
|
ieee80211_bss_conf
|
|
|
|
|
|
|
|
|
|
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 in AP mode.
