IIRC that's the xen PV driver.

A simple way to test whether xen pv net device is at fault is to use a
HVM domU but WITHOUT the pv drivers (there's a kernel commandline
argument that lets you have both emulated and PV device in the domU),
using the emulated NIC instead (e.g. e1000).

... and further investigation result might be more useful to
@xen-devel instead of @xen-users.
