Roaming (802.11r) support? #343

Any chance 802.11r support can be added to SPR? It would be a great addition as in multi-room environments having a working roaming setup is a must to handle for instance click-free voice calls when moving around.

Hi @bleedinge I will reevaluate this. With WPA2 there's a weakness with PMKIDs where an attacker can probe and get a hash to crack. With WPA3 802.11/fast transition is not well supported outside of 802.1x where there's a master PMK.

I want to look into if hostapd now has better WPA3 support for 802.11r/fast transition and if not I think we can put something together to distribute the PMK between mesh and AP.
