Supplying an EMAC address from the kernel command line


 * In the case of the DSK6455, we always pass the EMAC address to the kernel. This is shown below

CMDLINE = emac_addr=00:0e:1e:64:55:01 console=cio ip=dhcp rw


 * But in the case of the C6472 and C6474 we have 2 options
 * We can either pass the "emac_addr" as shown above to the kernel. In such cases the kernel will use the emac_addr' supplied to it.
 * If we do not supply an "emac_addr" in the kernel command line, then the driver will read the EMAC address from EFUSE registers.
