    Problem Text
    The test T.connect 4 sets association related options in a t_accept
    call and expects those options to be delivered to the connecting
    side of the connection in the T_CONN_CON.

    This won't work bexause TCP does an eager accept (SYN|ACK) before
    the connection is accepted by the application. This case is
    explicitly discussed in Appendix B section 3 of the XTI document.

    "If options with end-to_end significance (T_IP_OPTIONS, T_IP_TOS) are
    to be sent with the connection confirmation, the values of these options
    must be set with t_optmgmt() before the T_LISTEN event occurs. When
    the transport user detects the T_LISTEN, TCP has already established
    the connection. Association-related options passed with t_accept()
    become effective at once, but since the connection is already established,
    they are tranmitted with subsequent IP datagrams sent out in the
    T_DATAXFER state."

    Test Output

    ************************************************************************
    /tset/XTI.os/cots/connect/T.connect 4 Failed

    Test Description:
    If the implementation supports a connection-oriented transport
    service:
    When rcvcall is not NULL, and sndcall->opt.len is zero, then a
    successful call to t_connect( fd, sndcall, rcvcall ) returns
    information associated with the connection in rcvcall->opt.

    Test Strategy:
    VERIFY that the transport service is of type T_COTS or T_COTS_ORD
    MASTER:
    GENERATE a suitable option buffer for the transport provider using
    getoptlist() and addoption()
    OBTAIN an endpoint in T_IDLE state using provsetup()
    SEND the option buffer to the slave, using putsv_m()
    INITIATE a connection using t_connect() with sndcall->opt.len==0
    SLAVE:
    RECEIVE option buffer from the master, using getsv_s()
    WAIT for connect request using t_listen()
    ACCEPT connection using t_accept() with the options in call->opt
    MASTER:
    VERIFY that t_connect() returned zero
    VERIFY that rcvcall->opt has the expected contents

    Test Information:
    t_connect() on TCP endpoint
    Association-related option level <0> name <1> not found in rcvcall
    buffer
