====================
wireless-next patches for v6.2

Second set of patches for v6.2. Only driver patches this time, nothing
really special. Unused platform data support was removed from wl1251
and rtw89 got WoWLAN support.

Major changes:

ath11k

* support configuring channel dwell time during scan

rtw89

* new dynamic header firmware format support

* Wake-over-WLAN support

rtl8xxxu

* enable IEEE80211_HW_SUPPORT_FAST_XMIT
====================
