I deployed the recent canonical neutron-openvswitch charm that enables dpdk
with openvswitch as part of a test openstack setup.Bridges and ports are
configured properly and i am able deploy VM. Unfortunately I am not able to
learn macs or receive packets from the vhostuser ports. Packets are received
on the external and integration bridges (br-ex1 and br-int).I suspect this
might be something simple that i am missing. Any idea on how to fix this issue.
