   4 Subject: [PATCH 02/21] wifi: rtl8xxxu: prepare supporting two virtual
   5  interfaces
   6
   7 To prepare for concurrent mode, add an array ("vifs") to rtl8xxxu_priv
   8 to keep track of both interfaces.
   9
  10 Keep the old priv->vif as long there are still users of it and let
  11 priv->vifs[0] point to the same location.
