Greg Oster has what sounds like the identical problem on an ne2000.
But yes, its a good idea.
I've eyeballed Greg's traces, and he's getting packets with bad
checksums, due to what looks like a couple of mangled bits in the IP
total length field.
The MAC-level checksums aren't catching this, which in and of itself
points to a bug in our dp8390-handling code.
But just in case: Luke, what kind of cable modem do you have?
