ClosedPublic

Details

Summary

Move all PRR related cwnd update calculations into
a single function (formerly tcp_prr_partialack) and
move unique code to handle partial ACKs out.

This is in preparation for a more broad use of PRR
to handle ECN cwnd reductions, and non-SACK cwnd
reductions, as well as enhancements planned around
Lost Retransmission detection (continuation of a
PRR episode during LRD-induced, further cwnd reduction).

No functional change intended.

MFC to stable/13 after 2 weeks.
