802.11r (Fast Roaming) setup up for OpenWrt setup as a client

Hi all

I have a unifi network setup with fast roaming.

I want to roam with a small openwrt router but I can't find any documentation on how to setup an openwrt "client" in "r" mode.

All the documentation I can find is for setting up 802.11r from an OpenWRT router in AP (Master) mode.

Thanks

It seems to me that you can not because when you choose "client" mode, you have to enter a specific MAC address and only connect to it.
