I'm curious. Is the 'old' value with skb_zerocopy() or without? Does ovs-vswitchd 'read-access' the entire packet or just e.g. the header? I ask because in netfilter nfqueue tests I could not see any difference between 'zerocopy' vs. mmap in the receive-path tests I made a while back. [ I have no objections to your patch, of course ]. _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
