[PATCH 3/3] mac80211: allow using network namespaces

[Johannes Berg <johannes@sipsolutions.net>]

This finally opens up the ability to put mac80211 devices
into different network namespaces. As long as you don't
have sysfs, that is.

Semantically, this depends on both
  mac80211: cooperate more with network namespaces
and
  cfg80211: make aware of net namespaces

but in the code only the latter dependency is obvious,
so I'm sending it as a separate patch.
