raw ethernet packets

Hi,

I am trying to learn raw sockets and I have a specific question. I want to
send a custom Ethernet packet (non IP, ARP, PUP, RARP) to a specific
destination (whose address I don't know) through broadcast.

What do I need to do to process this packet at destination? Do I need to add
fields in netpacket/packet.h etc or can I simply receive all raw Ethernet
packets and process the one I need while ignoring other packets?

How will this packet be processed at other nodes in the network. Will the
device drivers of other nodes ignore the packet silently or will they
report/log any unknown packet received errors?

Thanks in advance for any pointers.

IP is networking protocol over Ethernet (on an Ethernet lan) and can
co-exist with other networking protocols harmoniously.

Google around for "raw Ethernet" and "programming ethernet frames"..
....amongst the links this came straight up
