The packet capture problem does not appear to have been fixed by the
bridge-nf-0.0.1-against-2.4.13-ac3.diff patch, applied against kernel
2.4.12. Although I can now see traffic both to and from the bridge
interface's IP address, I still can't see the traffic that is being
bridged.

Another problem is that I get a kernel panic when I run "rmmod
br_passthrough", whereas I usually get a "Device or resource busy" message
when I try to remove any other kernel module which is in use.
