parent[MCAST]: ip[6]_mc_add_src should be called when number of sources is zero (diff)
[TCP]: BIC max increment too large
The max growth of BIC TCP is too large. Original code was based on BIC 1.0 and the default there was 32. Later code (2.6.13) included compensation for delayed acks, and should have reduced the default value to 16; since normally TCP gets one ack for every two packets sent. The current value of 32 makes BIC too aggressive and unfair to other flows.
