Here's the kernelconfig (yes some stuff is double with GENERIC, we just want to
make sure these options are set):
include GENERIC

ident CUSTOM

options         DDB

options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_VERBOSE_LIMIT=5
options         IPFIREWALL_DEFAULT_TO_ACCEPT
options         IPDIVERT

device          pf
device          pflog
device          pfsync

device          enc

device          cpuctl

device          tuntap
