Stephen Hemminger 7752237e9f [TCP] TCP YEAH: Use vegas dont copy it.
Rather than using a copy of vegas code, the YEAH code should just have
it exported so there is common code.

Stephen Hemminger 164891aadf [TCP]: Congestion control API update.
Do some simple changes to make congestion control API faster/cleaner.
* use ktime_t rather than timeval
* merge rtt sampling into existing ack callback
  this means one indirect call versus two per ack.
* use flags bits to store options/settings

Eliminate need for full 6/4/64 divide to compute queue.
Variable maxqueue was really a constant.
Fix indentation.

Angelo P. Castellani 5ef814753e [TCP] YeAH-TCP: algorithm implementation
YeAH-TCP is a sender-side high-speed enabled TCP congestion control
algorithm, which uses a mixed loss/delay approach to compute the
congestion window. It's design goals target high efficiency, internal,
RTT and Reno fairness, resilience to link loss while keeping network
elements load as low as possible.
