Hi Dave,
as per earlier email, can you please revert the definition of the
TCP `before' relation: there is code which implicitly depends on it.
Furthermore, this definition appears in textbooks such as Stevens
and therefore, even if the newer definition may have nicer properties,
it is safer to stick with the old one.
--------------------> Patch <-------------------------------------
[TCP]: Use old definition of before
This reverts the new (unambiguous) definition of the TCP `before'
relation. As pointed out in an example by Herbert Xu, there is
existing code which implicitly requires the old definition in order
to work correctly.
