Subject: [PATCH net 0/2] macvlan: disable LRO on lowerdev instead of a macvlan

A customer of ours encountered a problem with LRO on an ixgbe network
card. Analysis showed that it was a known conflict of forwarding and LRO
but the forwarding was enabled in an LXC container where only a macvlan
was, not the ethernet device itself.

I believe the solution is exactly the same as what we do for "normal"
(802.1q) VLAN devices: if dev_disable_lro() is called for such device,
LRO is disabled on the underlying "real" device instead.

Michal Kubecek (2):
  macvlan: introduce IFF_MACVLAN flag and helper functions
  macvlan: disable LRO on lower device instead of macvlan
