Cannot put ath9k interface to different namespace?

Hi,

tried to put ath9k_htc interface to namespace, does not work:

jill:/home/ml # ip link set netns 4001 dev wlan3
RTNETLINK answers: Invalid argument

Also does not work with ath9k, but does work with other wlan devices
(tried zd1201, r8712u, thats what I've here at the moment).

When trying, device was down.

Is there some trick to do it or is there some support from driver for
that missing?

Any plans to fix that? Would that be big effort?

Thanks.
