nftables: no table for ipv6

[Thomas Witt <lists@thwitt.de>]

Hi, I am trying to configure nftables on a new server.

I can add tables for ip4:

# nft add table ip filter

but not for ip6 or inet:

# nft add table ip6 filter6
# nft add table inet filterboth
# nft list tables
table filter

So, a table gets added for ipv4, but not for v6. What do I need to do in
order for nft to support ip6? And why does nft returns 0 instead of an
error?

Versions:
nftables-0.3
libmnl-1.0.3
libnftnl-1.0.2

I tried kernels 3.15.6 and 3.16-rc7 with the following .config:
