From 2bbd7d584046038ce655e476628bb15e1460fac6 Mon Sep 17 00:00:00 2001

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