Warner Losh cb339c7cd9 SMC 8041 is the same thing as LINKSYS COMBO_ECARD, so no extra entry
is required.  NetBSD has one because it checks for the mac address
match as well wanting to give its own string in the description.
Since we do neither, we don't need a separate entry.

# I suspect that a few of the COREGA cards might fall into that category
# as well, but since I don't have access to any of them it is hard to know
# for sure.
