====================
One batch of changes, containing:
 * hwsim improvements from Jouni and myself, to be able to
   test more scenarios easily
 * some more HE (802.11ax) support
 * some initial S1G (sub 1 GHz) work for fractional MHz channels
 * some (action) frame registration updates to help DPP support
 * along with other various improvements/fixes
====================
