tcp: fix under-evaluated ssthresh in TCP Vegas
With the commit 76174004a0f19785 (tcp: do not slow start when cwnd equals ssthresh), the comparison to the reduced cwnd in tcp_vegas_ssthresh() would under-evaluate the ssthresh. Signed-off-by: Hoang Tran <hoang.tran@uclouvain.be> Signed-off-by: David S. Miller <davem@davemloft.net>
