No, OVS doesn't have an ability to grab arbitrary byte offsets into the packet. In general, I think there are too many corner cases for this to be the right solution for OVS to expose for most people. I would rather see an implementation of a flexible parser like P4 as the way to achieve this. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
