It turns out that the problem is indeed the different 0 offset that xt_bpf and
tcpdump use. In particular, it appears that offset 0 in tcpdump is at the very
beginning of the packet (ethernet header included) whereas xt_bpf uses the
beginning of the IP header. I've spoken with the author of the module, and he
is probably going to just point this out more clearly in the man pages.
