Very recent -STABLE.


>Description:
I have no INET6-related options in my kernel config.

When I am trying to 'kldload ipl' module, I get the following error:
link_elf: symbol in6_cksum undefined


>How-To-Repeat:
	
>Fix:

Tweak around USE_INET6 option in /sys/contrib/ipfilter/netinet/ip_compat.h
to cover the case when there is no INET6 in the kernel and ipfilter is
loaded as KLD.
