* 0/1 - 64 bytes written to TX FIFO before transmission of a frame begins.
* 2 - 128 bytes written to TX FIFO ....
* 3 - 192 bytes written to TX FIFO ....
* The maximum of txWatermark is 0x2F - 4032 bytes written to TX FIFO ....
* txWatermark allows minimizing the transmit latency to set the txWatermark to 0 or 1
* or for larger bus access latency 3 or larger due to contention for the system bus.
* 3. rxFifoFullThreshold is similar to the txWatermark for cut-through operation in RX.
* It is in 64-bit words. The minimum is ENET_FIFO_MIN_RX_FULL and the maximum is 0xFF.
* If the end of the frame is stored in FIFO and the frame size if smaller than the
* txWatermark, the frame is still transmitted. The rule is the
* same for rxFifoFullThreshold in the receive direction.
* 4. When "kENET_ControlFlowControlEnable" is set in the macSpecialConfig, ensure
* that the pauseDuration, rxFifoEmptyThreshold, and rxFifoStatEmptyThreshold
* are set for flow control enabled case.
* 5. When "kENET_ControlStoreAndFwdDisabled" is set in the macSpecialConfig, ensure
* that the rxFifoFullThreshold and txFifoWatermark are set for store and forward disable.
* 6. The rxAccelerConfig and txAccelerConfig default setting with 0 - accelerator
* are disabled. The "enet_tx_accelerator_t" and "enet_rx_accelerator_t" are
* recommended to be used to enable the transmit and receive accelerator.
* After the accelerators are enabled, the store and forward feature should be enabled.
* As a result, kENET_ControlStoreAndFwdDisabled should not be set.
