[PATCH] skge: handle VLAN checksum correctly on yukon rev 0
If using UDP over VLAN, with the skge driver there is a possibility
of generating an incorrect checksum. This is a unlikely occurrence
because it is only an issue on Yukon revision 0, and that revision
doesn't seem to exist on any current hardware (probably early prototype).
