Hi all,

Here's the full Accurate ECN implementation mostly based on
  https://tools.ietf.org/html/draft-ietf-tcpm-accurate-ecn-11

Comments would be highly appreciated. The GSO/TSO maze of bits
in particular is something I'm somewhat unsure if I got it
right (for a feature that has a software fallback).

There is an extensive set of packetdrill unit tests for most of
the functionality (I'll send separately to packetdrill).

Please note that this submission is not yet intented to be
included to net-next because some small changes seem still
possible to the spec.

ps. My apologies if you got a duplicate copy of them. It seems that
answering "no" to git send-email asking "Send this email?" might
still have sent something out.
