This changes the offsets for the MAC address location in mtd_get_mac_binary* and mtd_get_mac_text to hexadecimal notation. This will be much clearer for the reader when numbers are big, and will also match the style used for mtd-mac-address in DTS files. (e.g. 0x1006 and 0x5006 are much more useful than 4102 and 20486) Acked-by: Alexander Couzens <lynxis@fe80.eu> Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
