10 | * DOC: Station handling | |

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. | |
