There are functions in etherLib to let you filter all packets at the
ethernet level. See http://www.calsoftlabs.com/whitepapers/vxworks.html
for a description. However, I don't think that vxWorks allows a "raw"
socket type.

I have written a "new-style" vxWorks network stack driver and socket
interface for the IEEE802.2 LLC protocol, which may not be too difficult
to adapt for use as a raw socket interface. You'd have to trap a raw
flag on the socket creation call, and install the socket interface in
parallel with the existing implementations (which may or may not work).

I can let you have the LLC code if you like.
