10 * DOC: Station handling
11 *
12 * Stations are added per interface, but a special case exists with VLAN
13 * interfaces. When a station is bound to an AP interface, it may be moved
14 * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
15 * The station is still assumed to belong to the AP interface it was added
16 * to.
