This time we have too many changes to list, highlights:

Browse Source 
* virt_wifi - wireless control simulation on top of
    another network interface
  * hwsim configurability to test capabilities similar
    to real hardware
  * various mesh improvements
  * various radiotap vendor data fixes in mac80211
  * finally the nl_set_extack_cookie_u64() we talked
    about previously, used for
  * peer measurement APIs, right now only with FTM
    (flight time measurement) for location
  * made nl80211 radio/interface announcements more complete
  * various new HE (802.11ax) things:
    updates, TWT support, ...

This options enables support of Draft 802.11s mesh networking.
The implementation is based on Draft 2.08 of the Mesh Networking
