FYI, if we want to use the mac addr programmed into the SiByte MAC, then
the transmit descriptor needs to be modified to replace the source
address inserted by the DMA engine.  Right now in PROM, we rely on the
networking code to use the address from the SEEP.=20

Andy, do you know how the driver is working in Linux?  Does it setup the
MAC address for each packet or does it set the bit in the descriptor to
use the register value?
