Frankly, I think the main problem is that MAC_FMT got removed
for no real reason and is forcing us to come up with lots of
workarounds. We have NIPQUAD_FMT, NIP6_FMT, so I don't see
whats wrong with MAC_FMT. In fact I think a simple

printk(MAC_FMT, addr);

is much nicer than all this temporary buffer and function
call stuff.
