We have been using Xen as our vm only recently (about a year now).  We recently 
started to look at the tcp flow control that is coming in and out of the VM.  
Our configuration is that a physical interface on the host, peth1, is connect 
to vif1.1 by bridge br1, vif1.1 is instantiated as eth1 inside the vm.  We have 
a data source attached to eth1 that over subscribe the data capacity of peth1.  
Using pcap on all 4 location, we see that flow control is correctly enforced on 
peth1 but goes no further.  Is there a way to extend the flow control all the 
way into the vm onto eth1?

Thanks,
Ben Wang
