Ok, I looked at this, but I really need the ifname in more functions:

 - del_beacon (could be hacked around by looking at the bssid.. yuck)
 - set_beacon_int
 - set_sta_vlan
 - sta_set_flags
 - sta_remove
 - sta_add
 - flush
 - read_sta_data

For not all of the sta functions it is necessary, but since I'm trying
to move towards a "stations are per virtual interface" model in mac80211
it will probably become necessary, and at least sta_set_flags needs it
because of the 802.1x setting.
