ethernet mac address . in dts

drivers/net/ethernet ...
macaddr = of_get_mac_address(..)

drivers/of/of_net.c:

const void *of_get_mac_address(struct device_node *np)
{
    const void *addr;

    addr = of_get_mac_addr(np, "mac-address");
    if (addr)
        return addr;

    addr = of_get_mac_addr(np, "local-mac-address");
    if (addr)
        return addr;

    return of_get_mac_addr(np, "address");
}

grep 一下所有的 dts, mac-addr，結果都是 local-mac-address，少數有 mac-address.
但是形式都一樣..

       mac-address = [ 02 A1 A2 A3 A4 A5 ];
