Pretty sure this is already in the source tree as it sounds like the same as the alias fix:- http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ixgbe/ixgbe.c?rev=1.51;content-type=text%2Fplain There's also some additional fixes in the latest head version:- http://www.freebsd.org/cgi/cvsweb.cgi/src

Hi Andrew, could you please share the patch as I'm dying with this problem. What makes it worse is that on a busy router the DOWN/UP of the interfaces causes the ixgbe card to lose all network access until the box is rebooted. I can reproduce it easily on a variety of hosts from both HP and Dell.
