If you do that then it won't use Xen's checksum status fields. What needs to
happen is to make usage of the checksum offset independent of the checksum
status. Doing this requires first studying the different flavors Xen patches
for various kernel versions and seeing what is used in cases where both are
defined. Probably it's safe to use the new offset fields where they are defined
but it's not guaranteed to be true.
