It should work just fine; when I said "tcp_maxmtu" I really meant "tcp_maxmtu and tcp_maxmtu6". Of course, this all only affects TSO, and the netfront driver doesn't enable TSO for IPv6 (yet), so in a sense the real answer is "nothing at all". But the infrastructure will be in place for when it's needed. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid _______________________________________________ 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"
