The functions used by the congestion control mechanism are registered via passing a tcp_congestion_ops struct to tcp_register_congestion_control. As a minimum name, ssthresh, -cong_avoid, min_cwnd must be valid. +cong_avoid must be valid. Private data for a congestion control mechanism is stored in tp->ca_priv. tcp_ca(tp) returns a pointer to this space.
