Documentation on 802.11r

This is the config I ended up with (did it all on LuCi); this is the first AP:

        option reassociation_deadline '20000'

I tried to be clever and have the NAS ID the same as my BSSID and then r0kh and r1kh would be the same. The second AP:

config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'Redacted SSID'
        option encryption 'sae'
        option key 'redactedpsk'
        option ieee80211r '1'
        option ft_over_ds '0'
        option ft_psk_generate_local '0'
        option nasid 'E4:C3:2A:47:4A:3B'
        option reassociation_deadline '20000'
