I think there is a second problem with this patch:

If I create multiple station vdevs (on mtk7916 radio, not sure that matters much or not),
and admin up a few of them, but leave remainder down, then the queues on the originally-down-vdevs
are never started and so tx-path-hang on those stations.

I am not sure the best way to fix this.
