there are better approaches to this,
how about just calling:

	print_mac(dev->dev_addr);

Sure, we'll have to split up printk() calls, but in the end it's
likely still smaller and better.  And I think it's much cleaner
than this macro stuff.

My original patch had the equivalent of

	char* print_mac(char* buf, const char* addr) {
		sprintf(buf,"%02x:...", addr[0]...)
		return buf;
	}

and used:

	DECLARE_MAC_BUF(var); //same as char var[18];
	printk(MAC_FMT, MAC_ARG(var, addr));

which didn't require splitting printk()s

I've still got the original patch.
It's just substituting EUI48 for MAC and forward porting.

Want something like that?
