    tcp: adding a per-socket timestamp offset · ceaa1fef
    Andrey Vagin 提交于
    This functionality is used for restoring tcp sockets. A tcp timestamp
    depends on how long a system has been running, so it's differ for each
    host. The solution is to set a per-socket offset.
    
    A per-socket offset for a TIME_WAIT socket is inherited from a proper
    tcp socket.
    
    tcp_request_sock doesn't have a timestamp offset, because the repair
    mode for them are not implemented.
