I think you're looking at the kernel code but it's userspace that needs changes. OVS handles traffic on a flow basis so you would need to expand the flow and the logic that generates actions (which is based on comparing the flow from the original packet with a flow with modifications). If you do that then the kernel should already be able to insert multiple tags (although it matches on a single level with the standard EtherType). _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
