From 22e12e53b1378f0e3da23ea298dda59985d5b99b Mon Sep 17 00:00:00 2001
From: Florian Westphal <fw@strlen.de>
Date: Thu, 22 Sep 2022 13:33:50 +0200
Subject: [PATCH] nft: un-break among match with concatenation
The kernel commit 88cccd908d51 ("netfilter: nf_tables: NFTA_SET_ELEM_KEY_END requires concat and interval flags")
breaks ebtables-nft 'among' emulation, it sets NFTA_SET_ELEM_KEY_END but
doesn't set the CONCAT flag.
Update uapi header and also set CONCAT.
Signed-off-by: Florian Westphal <fw@strlen.de>
(cherry picked from commit 32efb4ffc33ae874b3f26f3380e2184ad6ceb26f)
