You usually set up WDS links between APs on the same channel, each
running both a normal AP vif and a WDS vif. The remote AP's beacons are
then used to detect the capabilities of the peer.
I don't think we can rely on "usually" unless we also enforce that
somehow. Otherwise this link will basically be dead. There's nothing
that requires you to add WDS to an AP interface only after all.
I don't think using WDS without APs makes any sense. Since WDS alone
does not use beacons or probe requests, there's nothing else that would
ensure that rate information, HT capabilities, etc. get exchanged.
