Trafshow uses bpf0 to do kernel level IP packet logging, etc.

So the pseudo device /dev/bpf0 must be in the kernel. To do this
add a line similar to this into the kernel config file:

pseudo-device   bpfilter 1

Then remake the kernel. For information on that see the handbook
under custom kernel of something like that.
