[TCP]: TCP cubic v2.2

We have updated CUBIC to fix some issues with slow increase in large
BDP networks. We also improved its convergence speed. The fix is in
fact very simple -- the window increase limit of smax during the
window probing phase (i.e., convex growth phase) is removed. We found
that this does not affect TCP friendliness, but only improves its
scalability. We have run some tests in our lab and also over the
Internet path from NCSU to Japan. These results can be seen from the
following page:
