is there any chance to include a macro like this for printing mac
addresses?
its advantage is that it can be used without the need to declare
buffers for
print_mac(), for example:
We specifically removed this sort of thing, please don't
add it back.

Why?

This results in print_mac getting called twice per packet even without
debugging. Whats the problem with MAC_FMT?
