The docs for the platform say that the attached PHY is a Broadcom 54616. I couldn't find any documentation on this PHY to determine what this value is (i.e. is it really some sort of ID string for that PHY). I almost suspect that the ixgbe is reading some registers on the PHY that just happen to contain this value after reset. Supposedly it's similar to the 54618 but that really doesn't provide much more information. The bnx2x has a driver for the 54618 and nothing that looks similar to that string.
