[Neutron] NUMA aware VxLAN
I'm curious. A lot of network cards support offloaded vxlan traffic these days so the processor isn't doing much work. Is this issue really a problem?

Existing neutron ML2 support one VxLAN for tenant network. In NUMA case, VM 0 can be created in node 0 and VM 1 can be created in node 1 and VxLAN is in node 0.
VM1 need to cross node, which cause some performance downgrade. Does someone have this performance issue? Does Neutron community have plan to enhance it?
