We are running an openstack instance with kernel 3.19 (due to some bugs in a Broadcom NIC we have in our server we had to use this particular kernel version) from Ubuntu 14.04.
The openvswitch build from our vendor is version 2.3.1 which our vendor only supports on version 3.13.
We have observed two issues so far when running in this configuration:

*         We had to disable GRO on the uplinks to our ovs, otherwise vxlan forwarding would stall

*         We encountered an issue this morning where on some vlans traffic would not be forwarded at all to the uplink
Is there a specific version (or set of patches) of openvswitch which would be recommended with this particular kernel version ? (3.19.0-30-generic)

Thank you,
Cristian Calin
