The issue is that dpdk support in OvS is limited to linux only.  Part of
the netdev-dpdk file has some linux specific calls, and the dpdk port
support relies on it.

Thanks.  It's an effort to support ovs+dpdk on freebsd (requires
development from OvS side).  OvS without DPDK ports is supported, but I
don't think that's of interested for the IOL DPDK testing right now.

I've CC'd the ovs mailing list - maybe someone is interested in writing
some patches :)  The most straight-forward thing I think is probably to
split out the vhost port support from the netdev-dpdk.c file somehow.
Then conditionally compile it in.  But there's probably a better way.
