[e2e] TCP out of order - idempotent packet/ack

[Jon Crowcroft]

there are some security reasons for having a nonce in a packet

if we did, we could identify each ack as "belonging" to a specific
transmission (including specific retransmissions) which would allow
full decoupling of rtt estimation ,bottleneck bandwidth estimation,
and reliablility


of course, it wouldn;t look much like TCP anymore, but it might work a
bit better, and be a lot simpler (looking at SACK DACK and other
processing nowdays is like trying to read hieroglyphics written
on fresh pasta
