802.11r + WPA3, does it work?

I got it working. Tested by running ping on mobile every 200ms and roaming. No dropped packets and ping spiked to 100ms at most.

Secret sauce:

	option ft_psk_generate_local '0'
	option max_inactivity '15'
	option dtim_period '3'
	option ieee80211w '2'
	option ft_over_ds '0'
	option reassociation_deadline '20000'

Also, you need to manually fill in the R0 and R1 keys. Automatic does not seem to work.

Taking down ERP to 20dB (100mW) is also helping devices to roam better. No point to radiate 200mW from AP if it cannot hear the device.
