   4 Subject: [PATCH 07/21] wifi: rtl8xxxu: extend check for matching bssid to both
   5  interfaces
   6
   7 The driver will support two interfaces soon, which both can be in
   8 station mode, so extend the check, whether cfo information should be
   9 parsed, to cover both interfaces.
  10
  11 For better code readability put the lines with priv->vifs[port_num] in a
  12 separate function.
