     * @group:       	4.3.6 FLOW CONTROL
     *
     * @description:	The device supports standard MAC Control PAUSE (802.3x flow control) frames in both the transmit and receive direc-
     *					tions for full-duplex connections.
     *					In the receive direction, if a PAUSE control frame is received on any port, the device will not transmit the next normal
     *					frame on that port until the timer, specified in the PAUSE control frame, expires. If another PAUSE frame is received
     *					before the current timer expires, the timer will then update with the new value in the second PAUSE frame. During this
     *					period (while it is flow controlled), only flow control packets from the device are transmitted.
     *					In the transmit direction, the device has intelligent and efficient ways to determine when to invoke flow control and send
     *					PAUSE frames. The flow control is based on availability of the system resources, including available buffers and avail-
     *					able transmit queues.
     *					The device issues a PAUSE frame containing the maximum pause time defined in IEEE standard 802.3x. Once the
     *					resource is freed up, the device sends out another flow control frame with zero pause time to turn off the flow control
     *					(turn on transmission to the port). A hysteresis feature is provided to prevent the flow control mechanism from being
     *					constantly activated and deactivated.
