This is an interesting observation, but I don't understand what you mean.
Explain "handling TCP segmentation" please? Exactly what chips do
that? What exactly do they do in the chip?
The chips might do IP fragmentation, but I find it hard to see how they
could do TCP segmentation, unless of course they are acting as a host.
Nothing wrong with a chipset being a host, too (perhaps to present a
web, ssh or SNMP interface).
