:)
Unless somebody can come up with a good argument for requiring the SSID?
I don't see it being necessary the way beaconing and everything is
designed in mac80211 now, and this leaves only the BSSID in the
interface config which I'll move to BSS config and then remove the
interface config thing completely.

Also, doesn't ieee80211_sta_config_auth already do exactly this
heuristic thing? If it doesn't know about the BSS it'll initiate a scan
for the SSID it's looking for?
