Subject: wireless vs. network namespaces

Now that the network namespace work is in net-2.6.24, I'm wondering how
wireless will be handling this. Is there any benefit at all to a
wireless device supporting network namespaces?

Should we, for now, set the new NETIF_F_NETNS_LOCAL flag for all
mac80211 devices?

If we do want to support moving, then we'll have to make cfg80211
(preferably, though mac80211 might be easier at first) migrate *all*
virtual interfaces associated with the same wiphy because otherwise
we'll get into trouble when moving one virtual interface and then
somebody in the other namespace changes its operating channel.
