Note that wlan-aware tools default to wlan0 (e.g. wlandebug, wlanstats)
so using "informative naming" will require extra typing. We are in need
of a lib80211 or similar and if/when that happens it'd be good to have a
routine that finds the most likely default network interface; e.g. by
scanning for wlanX interfaces that are cloned from an 802.11 interface.
