Dave,

Thank you for your response! Yeah, not having a unique PHY ID is somewhat disappointing :) I am trying to avoid flashing the ID on the board because then I need to know a serial number of the board when programming it and I can't seem to find a way to query the board for it (it seem to be on the packaging label only). I think I will generate MAC based on host's unique board serial number (/sys/devices/virtual/dmi/id/board_serial) and PCI device identifier (i.e. in what slot it is in). Just wanted to make sure that there isn't a unique PHY ID that I can piggyback onto :)

Thanks a lot for your response!
