Indeed, I should have checked more examples :/ There isn't any clear pattern
for this, so I guess any one would be ok.

Thanks. I'm ok with this, but maybe a native english speaker would have a
better opinion on this.

Thanks also, no more issue here.

One last thing, I noticed that you added:
+static int macaddr_internal_cmp(macaddr *a1, macaddr *a2);
but the existing function is declared as
macaddr_internal_cmp(macaddr *a1, macaddr *a2)
I'd be in favor to declare both as int.
After this, I think this patch will be ready for committer.
