When you say you are seeing timeouts I assume you mean dev_watchdog messages, and not the driver Tx hang messages. I have seen similar issues in the past and it is due to MSI-X interrupts being handled correctly by either Dom0 or Xen. You might try monitoring /proc/interrupts for the interface in question and see if interrupts are being delivered or not. You should see at least 1 interrupt every 2 seconds on the interface if it is up. If the interrupts are the issue then you might check with the Xen community to see if they are aware of any interrupt issues. The other option is to look at disabling MSI-X interrupts in the system to force the device to use either MSI or legacy IRQ.
