Hi Ben:

I checked the history for 2.11 and this patch is failing to backport due to
this commit
https://github.com/openvswitch/ovs/commit/5832e6a4f103a1eddd62c9ba459ce669e3a5d132
as it updates OVSB fast re-sync in news and its ported 2.12 . Hence,
backport to 2.12 worked. If we get
https://github.com/openvswitch/ovs/commit/5832e6a4f103a1eddd62c9ba459ce669e3a5d132
in
too to 2.11 it will apply cleanly. Let me know else I will have to amend
the news and it will fail backport for fast re-syc if we move that to 2.11
in future.
