look for "bpfilter" in /usr/src/sys/i386/conf/LINT and read "Configuring
the FreeBSD Kernel" in Handbook
http://www.freebsd.org/handbook/handbook50.html

#  The `bpfilter' pseudo-device enables the Berkeley Packet Filter.  Be
#  aware of the legal and administrative consequences of enabling this
#  option.  The number of devices determines the maximum number of
#  simultaneous BPF clients programs runnable.

pseudo-device   bpfilter        4       #Berkeley packet filter
