Using only the RTNL has a number of problems, most notably that ieee80211_iterate_active_interfaces() and other interface list traversals cannot be done from the internal workqueue because it needs to be flushed under the RTNL. This patch introduces a new mutex that protects the interface list against modifications. A more detailed explanation is part of the code change.
