Should also use is_broadcast_ether_addr and is_zero_ether_addr

It looks more like the rewrite is incorrect
as np is tested before of_get_property
It could be written something like:
if (is_broadcast_ether_addr(mac) || is_zero_ether_addr(mac)) {
bool assigned = false;
if (np) {
addr = of_get_property(np, "local-mac-address", &len);
if (len == ETH_ALEN) {
memcpy(mac_addr, addr, ETH_ALEN);
assigned = true;
}
}
if (!assigned) {
mac_addr[0] = 0x00;
mac_addr[1] = ...
}
}
