I did a sup -o today, and rebuilt everything, but I still get

# ipf -E

SIOCFRENB: Bad file descriptor
# ipf -f ipfrule

/dev/ipl: open: Operation not supported by device
# ls -l /dev/ipl
crw-------  1 root  wheel   29,   0 May 14 16:45 /dev/ipl

The ipfrule used to work, so what has changed? What am I missing?
