According to the RFC2001 in case of duplicate acks or timeout TCP has to
do slow-start until TCP has not the congestion window open to the value of
sstresh (set to max(cwnd/2,1) before -> at timeout time). When the
congestion window is >= sstrash, TCP must go in congestion avoidance
incrementing cwnd of segsize*segsize/cwnd and at most incrementing of 1
unit every RTT (this way cwnd increase liner and not exponential).
