[NET]: Undo code bloat in hot paths due to print_mac().
If print_mac() is used inside of a pr_debug() the compiler can't see that the call is redundant so still performs it even of pr_debug() ends up being a nop. So don't use print_mac() in such cases in hot code paths, use MAC_FMT et al. instead. As noted by Joe Perches, pr_debug() could be modified to handle this better, but that is a change to an interface used by the entire kernel and thus needs to be validated carefully. This here is thus the less risky fix for 2.6.25 Signed-off-by: David S. Miller <davem@davemloft.net>
