Johannes Berg says:
====================
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
====================
