Hi Jack & Colin,

Tried a ec2 c3 instance today and hit the same issue you noted on the
mailling list below last year
http://lists.freebsd.org/pipermail/freebsd-xen/2013-December/001817.html

The driver loads and shows a link status of active. But DHCP or other
traffic fails.

ix0: <Intel(R) PRO/10GbE Virtual Function Network Driver, Version - 1.1.4>
mem 0xf3000000-0xf3003fff,0xf3004000-0xf3007fff at device 3.0 on pci0

Just curious to know if either of you had any more information on a
potential workaround? Happy to provide access to an ec2 instance for you to
work/debug on if need be.

Regards Jarrod
