>Description:
I'm running on a computer with an Intel 10gigabit CX4 Dual Port network card. The FreeBSD version is 8.1 (but I also tried the 8.2) with the latest version of the ixgbe driver 2.2.3 got from the intel website.

The problem is the interface never goes up. An ifconfig shows "no carrier" for both ix0 and ix1 interface while the switch shows a functional 10gb link.

The nic works just fine with windows 7 and ubuntu 10.10 on the same computer.

I read somewhere, you needed to assign an IP to the interface in order to bring it up, doesn't work.

The man page states, I should contact "freebsdnic at mailbox.intel.com" if there are problems to report with the drivers but this email address doesn't work anymore.
>How-To-Repeat:
Just load the ixgbe driver and try to bring the interface up.
