    tcp: send packets with a socket timestamp · ee684b6f
    Andrey Vagin authored
    A socket timestamp is a sum of the global tcp_time_stamp and
    a per-socket offset.
    
    A socket offset is added in places where externally visible
    tcp timestamp option is parsed/initialized.
    
    Connections in the SYN_RECV state are not supported, global
    tcp_time_stamp is used for them, because repair mode doesn't support
    this state. In a future it can be implemented by the similar way
    as for TIME_WAIT sockets.
