3 Subject: [PATCH] netfilter: nf_tables: add single table list for all families
4
5 Place all existing user defined tables in struct net *, instead of
6 having one list per family. This saves us from one level of indentation
7 in netlink dump functions.
8
9 Place pointer to struct nft_af_info in struct nft_table temporarily, as
10 we still need this to put back reference module reference counter on
11 table removal.
12
13 This patch comes in preparation for the removal of struct nft_af_info.
