I think it would be useful to have a way to express this setup for systems with
many interfaces, but am unsure of where this should be described. Maybe a "mac-
address-offset" property in the generic ethernet controller binding?


May be something like eth_address_provider should be introduced in
net/ethernet/ ?

This provider can provide something like eth_provider_address_next() which
will consider "mac-address-num" (or other specific fields).

A patch series proposed the devicetree property
mac-address-increment, but it did not get support at the time:

Please have a look at some recent nvmem patches that adds support for vendor specific post-processing of nvmem-cells.

Am hoping that increment usecase (along with other variants) should also be dealt in similar way.
