MCF52233 FEC..

I’m writing a minimal Ethernet driver for the mcf52233 fec. I have noticed that when I configure a transmit buffer descriptor ring with only one descriptor, being the first and last in the ring. Each Ethernet frame that I launch is being transmitted twice by the hardware. When I configure two descriptors in the ring the problem goes away. Only one receive descriptor seams to be no problem. Any comment?
