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).

Some versions of the Marvell yukon generate bogus sensor warning interrupts.
The driver would flood log with these messages.  Handle this situation
