Merge tag 'wireless-next-2022-05-19' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
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 * tag 'wireless-next-2022-05-19' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (135 commits) iwlwifi: mei: fix potential NULL-ptr deref iwlwifi: mei: clear the sap data header before sending iwlwifi: mvm: remove vif_count iwlwifi: mvm: always tell the firmware to accept MCAST frames in BSS iwlwifi: mvm: add OTP info in case of init failure iwlwifi: mvm: fix assert 1F04 upon reconfig iwlwifi: fw: init SAR GEO table only if data is present iwlwifi: mvm: clean up authorized condition iwlwifi: mvm: use NULL instead of ERR_PTR when parsing wowlan status iwlwifi: pcie: simplify MSI-X cause mapping rtw89: pci: only mask out INT indicator register for disable interrupt v1 rtw89: convert rtw89_band to nl80211_band precisely rtw89: 8852c: update txpwr tables to HALRF_027_00_052 rtw89: cfo: check mac_id to avoid out-of-bounds rtw89: 8852c: set TX antenna path rtw89: add ieee80211::sta_rc_update ops wireless: Fix Makefile to be in alphabetical order mac80211: refactor freeing the next_beacon cfg80211: fix kernel-doc for cfg80211_beacon_data mac80211: minstrel_ht: support ieee80211_rate_status ... ==================== Link: https://lore.kernel.org/r/20220519153334.8D051C385AA@smtp.kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
