This updates mac80211 to version 6.1.145-1. This code is based on Linux 6.1.145 and contains all fixes included in the upstream wireless subsystem from that kernel version. This includes many bugfixes and also some security fixes. The removed patches were applied upstream. Link: https://github.com/openwrt/openwrt/pull/16948 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
