Yes, assuming your HW AP knows how to use such mode.

Hmm.. I would have to admit that I have not tested this at all. It can
be done with 1.5.x secondary firmware, but I'm not sure that the current
driver supports this. WDS links with another AP should be fine (i.e.,
neither one acting as a station). Having the other AP associate as a
station and then use 4-addr WDS frames might work, but it will probably
require manually adding the WDS link (iwpriv wds_add). In addition,
there might be something in the Host AP driver denying this kind of
link, since it was not designed to do that. Anyway, if you happen to
test this, please let me know if there are any problems and I'll try to
fix them.
