====================
wireless-next patches for v6.7

The first pull request for v6.7, with both stack and driver changes.
We have a big change how locking is handled in cfg80211 and mac80211
which removes several locks and hopefully simplifies the locking
overall. In drivers rtw89 got MCC support and smaller features to
other active drivers but nothing out of ordinary.

Major changes:

cfg80211
 - remove wdev mutex, use the wiphy mutex instead
 - annotate iftype_data pointer with sparse
 - first kunit tests, for element defrag
 - remove unused scan_width support

mac80211
 - major locking rework, remove several locks like sta_mtx, key_mtx
   etc. and use the wiphy mutex instead
 - remove unused shifted rate support
 - support antenna control in frame injection (requires driver support)
 - convert RX_DROP_UNUSABLE to more detailed reason codes

rtw89
 - TDMA-based multi-channel concurrency (MCC) support

iwlwifi
 - support set_antenna() operation
 - support frame injection antenna control

ath12k
 - WCN7850: enable 320 MHz channels in 6 GHz band
 - WCN7850: hardware rfkill support
 - WCN7850: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS to make scan faster

ath11k
 - add chip id board name while searching board-2.bin
