Shouldn't this check also be skipped if the orig parameter is a zero mac
address? i.e.:
if (!is_zero_ether_addr(orig)) {
if (!is_zero_ether_addr(entry->orig) && batadv_compare_eth(entry->orig,
orig))
continue;
}
Whether orig is zero can probably be checked once before the loop and the
result cached in a bool variable.
A little comment may also be nice to explain this part a bit better.
The rest looks good.
Cheers,
Simon
