Thread-topic: [Xen-devel] [PATCH] Fox for pcnet device model data corruption
Hi Dan,
   I am using i386 FC3 on the VMX guest. And x86_64 FC4 as the dom0
host. I am using the default config for bridge and networking, using the
   The data rate I am getting for scp from dom0 to vmx guest is 2.4MBps.

With the patch I have not seen any scp failures from dom0 to VMX guest.
It was comparatively easier for me to reproduce the VMX guest scp
problem on the same setup without the patch. Without the patch I was
also observing packets lost errors reported by the pcnet device in the
vmx guest. By design with the patch those errors should never come, and
that's what I am observing.

Thanks & Regards,
