Hi Todd,
Can you attach the output log of 'lspci -tv' and 'lspci -xxx -vvv'?

Attached.
 

I'm afraid you meet with the co-assignment limit.
If a device(including multi-function device) hasn't a proper standard FLR method, we have to use the SecondaryBusReset as a FLR method, so we require the co-assignment.
You can refer to http://xenbits.xensource.com/xen-unstable.hg?rev/e61978c24d84 for details.


Thanks for the information.

Let me know if there is anything else I can do.
 
Cheers,
Todd
