As far as I know, Eric and Tom are working on the kernel patch set and would submit a new version to net-next. Kernel patches usually go to netdev first and then backported to OVS tree. Meanwhile, this userspace patch works with current kernel module, with a limitation that inner VLAN header can not be matched, which should only impact the egress cvlan check. It would be nice if you could help try and review these patches. Regarding neutron part, Bo is working on it, and we are looking for a way to get OVS capabilities. Do you think it's better submit for discuss now or wait for the OVS part to be ready?
