- 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.
