I think it's better to remove the macro concatenation/obfuscation
of the NETIF_MSG_##level argument and simply pass the appropriate
NETIF_MSG_<type> directly to these ndev_<level> calls.

It would also simplify the more than 300 calls in drivers/net of

        if (netif_msg_<type>(ptr))
                printk(foo)

to

        ndev_<level>(netdev, NETIF_MSG_<type>, fmt, args)
