(This part will go away when devfs is really operational - hopefully only a
couple of months into the future)
Run the following lines as root:
# cd /dev
# ./MAKEDEF bpf[n]
where n is the maximum device number you want.
(This part will go away the day when we get bpf as a kernel module;
especially if it is demand-loaded :)
You will also need to compile a kernel with bpf enabled; copying this

into your kernel config and re-creating your kernel should do the trick.
(No, I haven't run mobile IP - I kan just comment on your problems with bpf.)
