Some older PC Cards have a weird format for FUNCE tuples. They appear
as type 0, rather than the usualy type 4. Assume that this format is
from an old standard and go with it. The Fujitsu FMV-186A and Silicom
Ethernet cards I have both have tuples with this format, and they are
both pretty old cards.
