Hello Bill, TSO is not supported on the T304 (not even with the 7.11.0 firmware). This is a 4 x gigabit card and you'll be able to max it out in either direction without TSO. > cxgbc0: Insufficient clusters and/or jumbo buffers. > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^???? ^^ this indicates you need to bump up the number of clusters and jumbos. Do so in /boot/loader.conf if you load if_cxgb early, or in /etc/sysctl.conf if you load it after the system has booted up: /boot/loader.conf: kern.ipc.nmbclusters=262144 /etc/sysctl.conf: kern.ipc.nmbclusters=262144 kern.ipc.nmbjumbo9=262144 kern.ipc.nmbjumbo16=262144 Regards, Navdeep _______________________________________________ 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"
