GRE and BPF

Hello all,
I've been having some trouble with a GRE tunnel. Specifically with
non-IP traffic (DECnet, in this case) and BPF.
I can see the GRE packets containing the DECnet packets coming over the
physical interface but when I do a tcpdump of bge0 I never see them.
This is an issue because the program I want to use will be using pcap to
pull packets off of the bge0 interface.
I can get IP packets off of the bge0 interface with tcpdump, however.
Is this just never going to work or am I missing something here?
The other end is a Cisco is it really matters.
I'm running:
FreeBSD wiggum 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243826: Tue Dec 4 06:55:39 UTC 2012 root at obrian.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
Thanks!
