On Topaz alt_bit is used only for port 0 for differentiating 100 mbps vs 200 mbps. The choices for SpdValue are 0 for 10 mbps, 1 for 100 mbps or 200 mbps (if alt_bit), 2 for 1000 mbps and 3 for 2500 mbps. 2500 is allowed only on port 5. alt_bit is not used on Topaz for port 5 (serdes), therefore I used !port.
