Subject: [PATCH v3 01/10] wifi: mac80211: Add EHT UL MU-MIMO flag in ieee80211_bss_conf
Date: Wed, 24 Apr 2024 13:19:50 -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.

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