If I can be so bold, the difference is that network nodes
are supposed to work and play together nicely, according to
well defined, published standards. Hardware has always been
completely random, and, to me at least, scary -- what standard
does any of it adhere to, other than, say, NE2000 cards? I've
yet to buy a network card (other than NE2000s) that promised
me much at all about its register structure, and I've certainly
been burned more than once by this. TCP/IP means something, and
folks oughta adhere to that definition.
I think that working around other people's frailties is a good thing,
in general, but the MSS clamping stuff is pretty close to where I draw
