Also note that TCP stack complexity has increased a lot, I seriously
doubt anyone could notice any difference.

During a hallway discussion with Eric Dumazet at Netdev 1.2 in
Tokyo some maybe-not-so-useful-anymore TCP stack features came up,
among these header prediction and prequeueing.
In brief, TCP prequeue assumes a single-process-blocking-read design,
which is not that common anymore. The most frequent

This RFC removes tcp prequeueing and header prediction support.
After a hallway discussion with Eric Dumazet some
maybe-not-so-useful-anymore TCP stack features came up, HP and
Prequeue among these.
So this RFC proposes to axe both.
In brief, TCP prequeue assumes a single-process-blocking-read
