3.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Vlad Yasevich <vyasevic@xxxxxxxxxx> [ Upstream commit 081e83a78db9b0ae1f5eabc2dedecc865f509b98 ] 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.
