If I remember correctly we have mac-address stored in various formats ex: from old thread I can see Type 1: Octets in ASCII without delimiters. (Swapped/non-Swapped) Type 2: Octets in ASCII with delimiters like (":", ",", ".", "-"... so on) (Swapped/non-Swapped) Type 3: Is the one which stores mac address in Type1/2 but this has to be incremented to be used on other instances of eth. Type 4: Octets as bytes/u8, swapped/non-swapped I think its right time to consider adding compatibles to nvmem-cells to be able to specify encoding information and handle post processing. Lets see what Rob would say on this approach. --srini > required: > - reg > >
