[ovs-dev] [PATCH] Add support for 802.1ad (QinQ tunneling)

[Mooney, Sean K]

Hi carl just reading thought this full thread now
But there are probably 2 usecase that we would like to use this for in neutron.
Vlan transparency for the ovs neutron network and as a qinq type driver.
We also might want to extend the vlan aware vms spec to support qinq at some point
So once this is available in ovs I think there are several places it could be beneficial
To consume it in neutron.
