maciotwo: change OHare MESH cell to MeshTnt.
...
It looks like the MESH cell inside OHare reports its version
in the old format, i.e. 0xEY where Y is >= 1.
Returning MESH ID in the new (Heathrow) format causes
the Native SCSI Manager to misrecognize the HW and crash badly.

grandcentral: Handle bit-flipping of MAC address.
...
If the ENET ROM begins with 0x10, then the bits of each byte are flipped 7..0 -> 0..7 which means the MAC address will begin with 0x08.
A MAC address beginning with 0x08 can be bit-flipped or not bit-flipped.
A MAC address cannot begin with 0x10.
I have a `dump-device-tree` output for a Power Mac 9500 with MAC address beginning with 08-00-07 (OUI for "Apple, Inc."). I don't know if it's using the bit-flipped ROM (starting with 10) or not bit-flipped ROM (starting with 08).
Most of the other `dump-device-tree` outputs I've seen have a MAC address beginning with an OUI for "Apple, Inc." that begins with 00.
