Subject: ip6tables filter breakage.

After updating to Linus' current tree with todays net/ merge,
I noticed that ip6tables doesn't work any more..

# ip6tables -F
ip6tables v1.4.19.1: can't initialize ip6tables table `filter': No
chain/target/match by that name
Perhaps ip6tables or your kernel needs to be upgraded

My config has CONFIG_IP6_NF_FILTER=m
I also note that ip6table_filter.ko doesn't get auto-loaded now.
But even after modprobing it, I get the same message.

Is there some additional option I now need to enable ?

I was a little surprised by how CONFIG_NF_TABLES is mandatory
for iptables to keep working, even if you don't have nft userspace.
(The only relevant thing in the Kconfig was related to x_tables,
 which I wasn't using).

Perhaps either some select's, or additional help text ?

	Dave
