I am just playing around with 802.11r (roaming). Just before going mad: what is implemented, what works, what is missing?
Is wpa_supplicant compiled with ieee80211=yes, what must be done to the backend mimikry?
802.11r can be done with open source stuff (actual openwrt works). iOS devices work and android devices could work but they have a wrong configuration mimikry.
If it does not work yet this would be a feature-request.
