I haven't touched this shit in ages but as I remember, the 1500 MTU of
Ethernet was a real drag on architectures with pages bigger than
1024* because it meant you always had to do one more memory copy.
Has anything changed in the past 15-20 years?

P.S. If you remember Berkeley Trailer Negotiation then
you know the era I'm talking about....
