* DOC: Station handling
*
* Stations are added per interface, but a special case exists with VLAN
* interfaces. When a station is bound to an AP interface, it may be moved
* into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
* The station is still assumed to belong to the AP interface it was added
* to.
*
* TODO: need more info?
