/* Function Name:
 *      rtk_ptp_portIntStatus_get
 * Description:
 *      Get PTP port interrupt trigger status.
 * Input:
 *      port           - physical port
 * Output:
 *      pStatusMask - Interrupt status bit mask.
 * Return:
 *      RT_ERR_OK           - OK
 *      RT_ERR_FAILED       - Failed
 *      RT_ERR_SMI          - SMI access error
 *      RT_ERR_INPUT        - Invalid input parameters.
 * Note:
 *      The API can get interrupt trigger status when interrupt happened.
 *      The interrupt trigger status is shown in the following:
 *      - PTP_INT_TYPE_TX_SYNC              (value[0] (Bit0))
 *      - PTP_INT_TYPE_TX_DELAY_REQ      (value[0] (Bit1))
 *      - PTP_INT_TYPE_TX_PDELAY_REQ    (value[0] (Bit2))
 *      - PTP_INT_TYPE_TX_PDELAY_RESP   (value[0] (Bit3))
 *      - PTP_INT_TYPE_RX_SYNC              (value[0] (Bit4))
 *      - PTP_INT_TYPE_RX_DELAY_REQ      (value[0] (Bit5))
 *      - PTP_INT_TYPE_RX_PDELAY_REQ    (value[0] (Bit6))
 *      - PTP_INT_TYPE_RX_PDELAY_RESP   (value[0] (Bit7))
