Not a bad idea..

But really this should be separate module(s) for each protocol type.
E.g.:

                     +-----------+
                     |  ng_iface |
                     +-----------+
                      /   |     \
                IPX  /    | IP   \  AppleTalk
           ... _____/     |       \_________________ ...
                          |        
                     +----------------+
                     | ng_ip_ethernet |
+--------------+     +----------------+              +----------------+
| ng_ipx_ether |       | ARP     | IP                | ng_atalk_ether |
+--------------+       |         |                   + (EtherTalk)    |
      |                |         |                   +----------------+
          ARP (0x0800) |         | IP (0x0800)               |
                       |         |
      IPX (0x8137)   +---------------+          AppleTalk (0x809B)
        ... ---------| ng_ether_mux  |--------------- ...
                     +---------------+
                           |
                           |
                     +-----------+
                     | ng_ether  |
                     +-----------+
