Perhaps you have already solved this one months ago, but ...

Do a "man 7 raw" - you can create two types of raw sockets, a "snoop"
socket which captures data-link frames with optional filtering (hence
puts the interface into promiscuous mode), and "drain" which allows
capture of frames for protocols that the kernel doesn't support.
The latter is typically used to create things like user-level Appletalk
drivers, it should allow you to capture ethernet frames of type "MOPD"
for example. I believe you can also transmit raw ethernet frames using
either type of socket.

P.S. I'm running IRIX 6.2 and 6.3, and my simple hacked-together packet
sniffer based on a snoop socket works fine on either OS.

Brian.
