From 7d34aa3e03b6a56306296bd98b26c6a1710cd57b Mon Sep 17 00:00:00 2001
From: Phil Sutter <phil@nwl.cc>

Subject: [PATCH] netfilter: nf_tables: Extend nft_expr_ops::dump callback
 parameters

Add a 'reset' flag just like with nft_object_ops::dump. This will be
useful to reset "anonymous stateful objects", e.g. simple rule counters.

No functional change intended.
