Raw Socket, EtherTalk datagram communication

The problem I'm trying to solve involves a Mac II running A/UX
with an EtherTalk interface card to an Ethernet LAN. The LAN
currently has datagrams being put on it by a microVax. The datagrams
are Ethernet datagrams (NOT Decnet, and NOT TCP/IP). I want to read
the datagrams with the MAC II. Do I use raw sockets which are
somehow linked to the EtherTalk board? How does the Internet address
relate to the 48-bit Ethernet address? How do I tell the EtherTalk
board which addresses it is supposed to listen to? I want to handle
multicast datagrams and I think I can do this using AARP (AppleTalk
Address Resolution Protocol). I have the Macintosh EtherTalk and
Alternate AppleTalk Reference Manual which describes this somewhat,
but doesn't go into much detail.
If anyone has any solutions, please answer by mail and I will
summarize all responses to the network.
