Merge tag 'wireless-next-2023-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next

Johannes Berg says:

====================
Major stack changes:

 * TC offload support for drivers below mac80211
 * reduced neighbor report (RNR) handling for AP mode
 * mac80211 mesh fast-xmit and fast-rx support
 * support for another mesh A-MSDU format
   (seems nobody got the spec right)

Major driver changes:

Kalle moved the drivers that were just plain C files
in drivers/net/wireless/ to legacy/ and virtual/ dirs.

hwsim
 * multi-BSSID support
 * some FTM support

ath11k
 * MU-MIMO parameters support
 * ack signal support for management packets

rtl8xxxu
 * support for RTL8710BU aka RTL8188GU chips

rtw89
 * support for various newer firmware APIs

ath10k
 * enabled threaded NAPI on WCN3990

iwlwifi
 * lots of work for multi-link/EHT (wifi7)
 * hardware timestamping support for some devices/firwmares
 * TX beacon protection on newer hardware

* tag 'wireless-next-2023-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (181 commits)
