Does the raw Ethernet packet socket API help you? It should allow you to
receive any packets (not just IP). I am unfamiliar with it though, but
look for it in the src/core/ directory.

Another idea: pbuf_ref() any incoming IP packet and pass it to the lwIP
stack, but also pass it to your packet logger/analyzer (and pbuf_free it
there after use).

It was well written, I just hope I took enough time to really see what
you try to accomplish.

Good luck,

Leon.
