You can see the result above: the check_pkt_len() shows a branch on size=2, with the size>2 case inside gt() and the size<=2 case inside le(). size=2 doesn't seem like the size you care about though. Was it what you specified? > How can I check the reg[0] value was set? It's more of a "what-if" game in this case, since the generated flow considers both possibilities. > I suspect that the register is set but the next flow ignores the value in the > match. _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
