|| ||[RFC 0/3] TCP congestion control RTT patches|

These patches deal with issues brought up by Gavin McCullagh
about reactions of Cubic and HTCP to hostile receivers that return
bogus timestamp options. In a couple of places the timestamp value
is used in ways that could cause unfairness.
The solution in these patches is to only use local values to measure
RTT for congestion control. The timestamp is still used as described
in RFC's to measure RTT used for retransmit timer.
This code is preliminary and not throughly tested yet. It could
be backported to 2.6.22 for stable kernels, but it would be hard to
go back to earlier kernels because it builds on the recent TCP congestion
control API changes.
