Boards with multiple ethernet ports might store their MAC addresses not
individually per port but just store one base MAC address. To get the
MAC address of a specific network port we have to add an offset.

Due to possible mode switching to 8D-8D-8D, it might not be possible to
read the SFDP after the initial probe. To be able to dump the SFDP via
sysfs afterwards, make a complete copy of it.

8D-8D-8D mode. Instead, cache the SFDP data
- add two sysfs files: jedec-id and name
- change the file mode of the sfdp file from 0400 to 0444. There is no
