I think this sort of patch should come as the first
patch in a series with some example conversions.

It might be too easy to confuse is_broadcast_ether_addr
with this function name too.  Maybe set_broadcast_ether_addr
might be better.

I really don't see an issue with using memset though.
Everyone already knows what that does.
