I propose ephemeral but permanent NETMAP RX pipe with redistribution function from user-loadable kernel module. Hardware RxRing(i) => loadable hash => user-visible RxRing(j). As I perceive overhead is packet-parsing and hash computation + swaping of slot indexes (zero-copying between hardware ring and user-visible ring). In other (Tx) direction user-visible direct mapped to hardware ring. > If it's inside GRE, then it's IPv4/IPv6 and thus yes, you can do > symmetric hashing. But if it's raw pppoe coming in, you're SoL. This is will be only hashed tunnel IPs, yes? Not sessions inside tunnel. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
