you mean that I should send below by separate patch? It seemed that I
misunderstood, I use the ./script/getmainter and found the only maintainer
is David, and others are support, so maybe I was wrong, but it really a big
patchset, could I send them by seperate patchset? I think it could be more
clearly.

Agree, I make it in the early patchset, as same as yours,
[PATCH net-next 1/6] bonding: use ether_addr_equal_unaligned for bond addr
compare
in my opinion, I think it would be better in the bonding patchset,
because I am making a patchset for bonding.
