From ba6cc7f6f194e3645368f87d951bedd7e3b75f39 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Fri, 1 Apr 2016 13:34:31 -0700 Subject: [PATCH] i40evf: properly handle VLAN features Correctly set the VLAN feature flags after setting the rest of the netdev flags. And don't set them in hw_features, because these can't be controlled by the VF driver.
