Hi,

Please backport the following patch back to the stable series 6.6 and 6.1: commit a8bca3e9371dc5e276af4168be099b2a05554c2a Author: Johannes Berg johannes.berg@intel.com Date: Wed Feb 28 12:01:57 2024 +0100

wifi: mac80211: track capability/opmode NSS separately

There is a small conflict in the copyright year update in net/mac80211/sta_info.h, just take the 2024 version.

On kernel 6.1 please backport this patch first to make the other one apply: commit 57b341e9ab13e5688491bfd54f8b5502416c8905 Author: Rameshkumar Sundaram quic_ramess@quicinc.com Date: Tue Feb 7 17:11:46 2023 +0530

wifi: mac80211: Allow NSS change only up to capability

This commit fixes a throughput regression introduced into Linux stable with the backport of following commit:

commit dd6c064cfc3fc18d871107c6f5db8837e88572e4 Author: Johannes Berg johannes.berg@intel.com Date: Mon Jan 29 15:53:55 2024 +0100

wifi: mac80211: set station RX-NSS on reconfig

On older kernel versions it is harder to backport the fixes, maybe revert the offending commit in Linux stable 5.15 and older.

This regression was found by multiple users of OpenWrt in Wifi AP mode. See the discussion in this forum thread: https://forum.openwrt.org/t/openwrt-23-05-4-service-release/204514/111

Thank you KONG from the OpenWrt forum for finding the commit which reduced the Wifi throughput.

This is a bit complex, please provide a series of backported patches for each tree that you have tested and done the needed changes to get working properly. Otherwise, the above descriptions are going to take a long time for us to get to, sorry, as we have much more "simpler" things to backport at this point in time.

thanks,
