The issue is about whether the hardware can segment
the large piece of data into segments of different
sizes. I understand that TCP can send down different
sizes of segment and ask the hardware not to segment
them. But this is basically the same as today, send
down one segment one time. What I am referring to is
the ability to send down a large piece of data and ask
the hardware to segment it into different sizes, say
one large and then three shorter. This is one way
how TCP can find out if PMTU has changed.
