Help! Network issue with freebsd + Xen

[Alex]

Hi guys,

I am having an issue with high network interface collisions when running 
freebsd under XEN (I am using freebsd as my OS for a VPS).

I have filed a PR at http://www.freebsd.org/cgi/query-pr.cgi?pr=154236 
and have had some discussion with the driver maintainer, we're both at a 
loss as to what the issue is, perhaps someone here could take a look at 
it and see whether they have seen the same issue or know what may be 
causing it.
