3.2.63-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Yasevich <vyase...@redhat.com>
[ 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.
