OK, I understand where Tom was going. Given we add feature detection capabilities this could be used to identify the guest for fixed length encap. I still assume HW won't be able to match on the inner header for any variable lengh encap with metadata packet unless it can actually parse the encap. I hope I didn't bring encap format to this thread at this very moment ;-) _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
