Kalle Valo says:

====================
wireless-next patches for v5.19

Second set of patches for v5.19 and most likely the last one. rtw89
got support for 8852ce devices and mt76 now supports Wireless Ethernet
Dispatch.

Major changes:

cfg80211/mac80211
 - support disabling EHT mode

rtw89
 - add support for Realtek 8852ce devices

mt76
 - Wireless Ethernet Dispatch support for flow offload
 - non-standard VHT MCS10-11 support
 - mt7921 AP mode support
 - mt7921 ipv6 NS offload support

ath11k
 - enable keepalive during WoWLAN suspend
 - implement remain-on-channel support
