====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next.
Basically, more incremental updates for br_netfilter from Florian
Westphal, small nf_tables updates (including one fix for rb-tree
locking) and small two-liner to add extra validation for the REJECT6
target.

More specifically, they are:

1) Use the conntrack status flags from br_netfilter to know that DNAT is
   happening. Patch for Florian Westphal.

2) nf_bridge->physoutdev == NULL already indicates that the traffic is
   bridged, so let's get rid of the BRNF_BRIDGED flag. Also from Florian.

3) Another patch to prepare voidization of seq_printf/seq_puts/seq_putc,
   from Joe Perches.

4) Consolidation of nf_tables_newtable() error path.

5) Kill nf_bridge_pad used by br_netfilter from ip_fragment(),
   from Florian Westphal.

6) Access rb-tree root node inside the lock and remove unnecessary
   locking from the get path (we already hold nfnl_lock there), from
   Patrick McHardy.

7) You cannot use a NFT_SET_ELEM_INTERVAL_END when the set doesn't
   support interval, also from Patrick.

8) Enforce IP6T_F_PROTO from ip6t_REJECT to make sure the core is
   actually restricting matches to TCP.
