If the PHY reports an incorrect ID (or none at all) then the
compatible list may contain an entry with the correct PHY ID
in the above form.
The first group of digits is the 16 bit Phy Identifier 1
register, this is the chip vendor OUI bits 3:18. The
second group of digits is the Phy Identifier 2 register,
this is the chip vendor OUI bits 19:24, followed by 10

If set, indicates that the PHY is integrated into the same
physical package as the Ethernet MAC. If needed, muxers
should be configured to ensure the integrated PHY is
used. The absence of this property indicates the muxers
should be configured so that the external PHY is used.
