This adds hwsim test ap_vlan_iface_cleanup_multibss. It connects two stations in different BSS but the same hostapd process. First both stations are in VLAN 1, then they get reauthenticated into VLAN 2. Due to the ordering of the stations moving around, this test checks that bridge and tagged interface referencing counting is done globally, such that the tagged interface is not removed too early and no bridge is left over.
