The earlier patch that Ben is referring to is this one from Peter
O'Gorman:

http://seclists.org/nmap-dev/2011/q4/349
http://seclists.org/nmap-dev/2011/q4/353
http://seclists.org/nmap-dev/2011/q4/att-353/aix.patch
https://code.google.com/p/libdnet/issues/detail?id=23

I've just applied the part of the patch that causes
sa.sndd_8022_ethertype to be set to 0 rather than ETH_TYPE_IP. That
worked for Peter but not for Ben.

It might help if you can try to compile and run this example code from
IBM. If its bind works, but that of eth-ndd.c doesn't, then we can
identify what the important differences are.
