Personally, when I see things that are different, I start wondering about
why. So if there is no reason for it to be different, I would prefer that
it is the same.

Certainly, a mac_addr type is more meaningful than just an array with size
ETH_ALEN, or worse an array with size 6. But I am not sure that it is
practical to introduce that type everywhere.

In any case, it is not a big issue.
