Message-Id: <1406817025-17738-1-git-send-email-vyasevic@redhat.com> Date: Thu, 31 Jul 2014 10:30:25 -0400 From: Vlad Yasevich <vyasevic@...hat.com> To: netdev@...r.kernel.org Cc: Vlad Yasevich <vyasevic@...hat.com> Subject: [PATCH net] macvlan: Initialize vlan_features to turn on offload support. Macvlan devices do not initialize vlan_features. As a result, any vlan devices configured on top of macvlans perform very poorly. Initialize vlan_features based on the vlan features of the lower-level device.
