The module is called "ipl.ko":

# ls -l /boot/kernel/ipl.*
-r-xr-xr-x  1 root  wheel  - 171625 May 16 16:05 /boot/kernel/ipl.ko
-r-xr-xr-x  1 root  wheel  - 371887 May 16 16:05 /boot/kernel/ipl.ko.symbols
#

Strange and weird, but this is the name the IP Filter kernel module
has had for years, so it's not easy to change it now without breaking
all the scripts around the world that assume its name is "ipl".
