Right now, the userspace needs to give the exact AP_VLAN interface index for CMD_FRAME; hostapd does not do this. Additionally, userspace cannot use GET_STATION to query the AP_VLAN ifidx, as while GET_STATION finds stations assigned to AP_VLAN even if the AP iface is queried, it does not return AP_VLAN ifidx (it returns the queried one). This breaks IEEE 802.11r over_ds with vlans, as the reply frame does not get out. This patch fixes this by using get_sta_bss for CMD_FRAME.
