That makes sense.
I was wondering whether we should get rid of batadv_compare_eth() at all
and always use ether_addr_equal_unaligned(). The "unaligned explanation"
is part of the name, so there is no need to use a commented helper anymore.
However, until that moment it is better to get stuck to
batadv_compare_eth().
Ding, can you also follow Joe's suggestion for this patch please?
Thanks,
