From e38f30256b36700aa63aa709dc091bf6eb69c257 Mon Sep 17 00:00:00 2001 From: Toshiaki Makita Date: Fri, 27 Mar 2015 14:31:13 +0900 Subject: [PATCH] net: Introduce passthru_features_check As there are a number of (especially virtual) devices that don't need the multiple vlan check, introduce passthru_features_check() for convenience.
