   4 Subject: [PATCH 09/21] wifi: rtl8xxxu: support setting bssid register for
   5  multiple interfaces
   6
   7 To prepare for concurrent mode, enhance rtl8xxxu_set_bssid() to write the
   8 BSSID of the respective interface to REG_BSSID or REG_BSSID1.
   9
  10 Like done with rtl8xxxu_set_mac(), call rtl8xxxu_set_bssid() with
  11 port_num = 0, until the callers also support multiple interfaces.
