   4 Subject: [PATCH 10/21] wifi: rtl8xxxu: support multiple interfaces in
   5  set_aifs()
   6
   7 In concurrent mode supported by this driver, both interfaces will use
   8 the same channel and same wireless mode.
   9 It is therefore possible to get the wireless mode by checking the first
  10 connected interface.
