Please use a module_param() instead of a top level kernel parameter.

You may also consider using module_param_array() here. See 
drivers/net/ethernet/freescale/fec.c for an example. Note, however, that this 
changes the format the MAC address representation. Instead of 
"01:02:03:04:05:06", use "0x01,0x02,0x03,0x04,0x05,0x06".
