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.
