    tcp: Make PAWS robust against segments reordering
    
    This tends to prevent valid new segments from being dropped by the
    reordered segments sent by the fast retransmission algorithm on the
    sending side, i.e. the fast retransmitted segment w/ larger timestamp
    arrives earlier than the previously sent new segments w/ smaller
    timestamp, which causes the valid new segments being dropped.
