>Description:
	Inability to use ipfilter module (ipl.ko) with custom kernels w/o INET6

	# kldload ipl
	kldload: can't load ipl: No such file or directory
	# dmesg|tail -1
	link_elf: symbol in6_cksum undefined

>How-To-Repeat:
	Remove INET6 from kernel configuration file, recompile and install new kernel, "kldload ipl"
>Fix:

Honour NOINET6 in module build.
