Subject: [PATCH 01/10] wifi: mac80211: Add EHT UL MU-MIMO flag in ieee80211_bss_conf
Date: Mon, 25 Mar 2024 13:10:22 -0700

Add flag for Full Bandwidth UL MU-MIMO for EHT. This is utilized
to pass EHT MU-MIMO configurations from user space to driver in
AP mode.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
