Set sa.sndd_8022_ethertype to 0 in eth-ndd.c.

Browse Source 
This file is used for Ethernet handles on AIX. We had a report from
Peter O'Gorman that setting this member to 0 rather than ETH_TYPE_IP was
necessary to avoid an EEXIST error on bind.

However Ben Lentz more recently tried the patch and said that he still
got an EEXIST on bind.

So who knows what the right thing to do here is. The messages from IBM
seem to say that setting ETH_TYPE_IP is definitely wrong though.
