Log:
DCTCP (Data Center TCP) implementation.
DCTCP congestion control algorithm aims to maximise throughput and minimise
latency in data center networks by utilising the proportion of Explicit
Congestion Notification (ECN) marked packets received from capable hardware
as a
congestion signal.
Highlights:
Implemented as a mod_cc(4) module.
ECN (Explicit congestion notification) processing is done differently from
RFC3168.
Takes one-sided DCTCP into consideration where only one of the sides is using
DCTCP and other is using standard ECN.

Huge thank you!
FWIW, I thought the linux guys wouldn't take it over some GPL vs patent
issue but apparently redhat pushed some muscle and just did it:

Not that I care much what they do ;).
