How about trying to use bluetooth like a loopback device ?
If this is possible, I think we should define BLUETOOTH as a kernel
config parameter like we do for INET, INET6, NETISO, etc.

No, I don't think so. /etc/protocols seems wrong. Also, this file is
out of date. I'm going to update it.

What does lint say if you change filter->mask to unsigned ?
