[PATCH v4 00/12] some UHR support

[Johannes Berg]

Changes since v3:
 - fold in the hostapd_set_freq_params() change
 - add more DBE code
 - move to always using MLO for UHR
 - fix EHT BPCC
 - add UHR critical update field

Most of these are because I'm making some changes in mac80211
as well:
 - will require MLO for UHR because of critical updates in MLE,
   this in turn requires security
 - will require enhanced critical update in MLE
