Kalle Valo says:
====================
wireless-next patches for v6.8
The third "new features" pull request for v6.8. This is a smaller one
to clear up our tree before the break and nothing really noteworthy
this time.
Major changes:
stack
* cfg80211: introduce cfg80211_ssid_eq() for SSID matching
* cfg80211: support P2P operation on DFS channels
* mac80211: allow 64-bit radiotap timestamps
iwlwifi
* AX210: allow concurrent P2P operation on DFS channels
====================
