Stephen Hemminger 30cfd0baf0 [TCP]: congestion control API pass RTT in microseconds
This patch changes the API for the callback that is done after an ACK is
received. It solves a couple of issues:

  * Some congestion controls want higher resolution value of RTT
    (controlled by TCP_CONG_RTT_SAMPLE flag). These don't really want a ktime, but
    all compute a RTT in microseconds.

  * Other congestion control could use RTT at jiffies resolution.

To keep API consistent the units should be the same for both cases, just the
resolution should change.

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.
