From d6ae3505ac6c0e34ca2a209d4ac9ffe9ad87575d Mon Sep 17 00:00:00 2001 From: Deren Wu Date: Tue, 7 Jun 2022 13:00:46 +0800 Subject: [PATCH] mt76: enable the VHT extended NSS BW feature According IEEE Std 802.11-2020, its definition is: Indicates whether the STA is capable of interpreting the Extended NSS BW Support subfield of the VHT Capabilities Information field. Some APs, such as Xiaomi AX6000, would check this one for BW settings. mt76 driver can get max BW capability only if the this field is confgured properly.
