Just a quick follow-up. We figured out a way to do it with the "basic" filter that allows us to specify the policer just on the interface and doesn't require limiting it to a particular protocol. While doing that I'm also reworking the code to directly make the netlink calls as opposed to shelling out to the "tc" program, which Jamal pointed out was kind of sloppy on the netdev mailingn list. I should have that patch out by tomorrow evening with both of those cleanups. --Justin _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
