Why would you want to have WDS? IMHO if you really want to do it over
wifi it makes more sense to use 4-addr AP/client. That at least gives
you a reasonable configuration one might use in the real world - WDS
can't negotiate HT/VHT for example, making it pretty much useless these
days.

It may work in hwsim, but I don't really want to encourage such usage.
I'd even argue that we should just remove support for this from the
kernel entirely, but that will probably not happen.
