I ... don't see how you would implement that by defining just a feature
bit?! And you have no documentation for how it'd be implemented, nor any
additional code in mac80211, though that would seem to be necessary
given that it also queues frames?
IOW, "driver supports forwarding" doesn't make much sense without other
mechanisms _somewhere_, and then those should be described (perhaps in a
new nl80211.h DOC: section, which is probably a good idea for the whole
SMD AP-side anyway).
