Details:

Currently I need to do this in my code:


    struct netif *netif = netif_add(&ethernet_netif,
#if LWIP_IPV4
                                    NULL, NULL, NULL,
#endif
                                    NULL, &ethernetif_init, &tcpip_input);


I think that's unnecessarily ugly. How about the following addition to the
netif API to avoid this?


#if LWIP_IPV4
# define netif_add_no_addr(netif, state, init, input) \
    netif_add(netif, NULL, NULL, NULL, state, init, input)
#else
# define netif_add_no_addr(netif, state, init, input) \
    netif_add(netif, state, init, input)
#endif /* !LWIP_IPV4 */
