Subject: [PATCH net v2 0/2] macvlan: disable LRO on lowerdev instead of a macvlan
Date: Thu, 14 Nov 2013 15:00:06 +0100 (CET) [thread overview]
Message-ID: <cover.1384436410.git.mkubecek@suse.cz> (raw)
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.
v2: adapt to changes merged from net-next
Michal Kubecek (2):
macvlan: introduce macvlan_dev_real_dev() helper function
macvlan: disable LRO on lower device instead of macvlan
