Sure.  What I'm driving at is that a checksum of zero seems to imply 
CHECKSUM_NONE not CHECKSUM_UNNECESSARY.  tg3 only does the 0xffff check.

Sure, both ways are fine.

huh?  They are pretty different...  one says "Checksum all good, dude" 
and the other says "I didn't checksum, do it in software for me."

right?

0x0000 is the UDP "no checksum" case, so if we say "in software"
for that UDP will just let it pass through still, so the effect
is that same.
