[PATCH v2 1/3] wifi: cfg80211: do not support direct add of station to AP_VLAN interfaces

[Slawomir Stepien]

Prevent userspace from adding stations directly to AP_VLAN type
interfaces. Userspace should first add the station to the base interface
(AP type) and then can use CMD_SET_STATION to move it to AP_VLAN. The
other way is by using NL80211_ATTR_STA_VLAN.

Without this path, we cannot check if the AP has been started before
adding the station - wdev for AP_VLAN does not store information about
the base AP interface.
