====================
wireless-next patches for v6.11

Most likely the last "new features" pull request for v6.11 with
changes both in stack and in drivers. The big thing is the multiple
radios for wiphy feature which makes it possible to better advertise
radio capabilities to user space. mt76 enabled MLO and iwlwifi
re-enabled MLO, ath12k and rtw89 Wi-Fi 6 devices got WoWLAN support.

Major changes:

cfg80211/mac80211
 * remove DEAUTH_NEED_MGD_TX_PREP flag
 * multiple radios per wiphy support

mac80211_hwsim
 * multi-radio wiphy support

ath12k
 * DebugFS support for datapath statistics
 * WCN7850: support for WoW (Wake on WLAN)
 * WCN7850: device-tree bindings

ath11k
 * QCA6390: device-tree bindings

iwlwifi
 * mvm: re-enable Multi-Link Operation (MLO)
 * aggregation (A-MSDU) optimisations

rtw89
 * preparation for RTL8852BE-VT support
 * WoWLAN support for WiFi 6 chips
 * 36-bit PCI DMA support

mt76
 * mt7925 Multi-Link Operation (MLO) support
