+ * @Descr: Ethernet driver for the NS9750. Uses DMA Engine with polling
+ *	   interrupt status. But interrupts are not enabled.
+ *	   Only one tx buffer descriptor and the RXA buffer descriptor are used
+ *	   Currently no transmit lockup handling is included. eth_send has a 5s
+ *	   timeout for sending frames. No retransmits are performed when an
+ *	   error occurs.
