[PATCH 2/4] mac80211: set NET_NAME_USER for user-space created ifs

[David Herrmann]

The nl80211 interface allows creating new netdevs from user-space. The
name is *always* provided by user-space, so we should set NET_NAME_USER to
provide that information via sysfs.

This allows udev to not rename dynamically created wifi devices (like wifi
P2P devices).
