   4 Subject: [PATCH 15/21] wifi: rtl8xxxu: support multiple interfaces in
   5  bss_info_changed()
   6
   7 Call set_linktype and set_bssid now with correct port_num. Call
   8 stop_tx_beacon only for port 0, as we don't support beacons on port 1.
   9 Explicit changes to BEACON will only happen for AP type interfaces, so
  10 we don't need an additional check there.
