    tcp_htcp: last_cong bug fix · 8f65b535
    Doug Leith authored
    This patch fixes a minor bug in tcp_htcp.c which has been
    highlighted by Lachlan Andrew and Lawrence Stewart.  Currently, the
    time since the last congestion event, which is stored in variable
    last_cong, is reset whenever there is a state change into
    TCP_CA_Open.  This includes transitions of the type
    TCP_CA_Open->TCP_CA_Disorder->TCP_CA_Open which are not associated
    with backoff of cwnd.  The patch changes last_cong to be updated
    only on transitions into TCP_CA_Open that occur after experiencing
    the congestion-related states TCP_CA_Loss, TCP_CA_Recovery,
    TCP_CA_CWR.
