Subject: net, ip_tunnel: fix namespaces move
From: William Dauchy <w.dauchy@xxxxxxxxxx>
[ Upstream commit d0f418516022c32ecceaf4275423e5bd3f8743a9 ]
in the same manner as commit 690afc165bb3 ("net: ip6_gre: fix moving
ip6gre between namespaces"), fix namespace moving as it was broken since
commit 2e15ea390e6f ("ip_gre: Add support to collect tunnel metadata.").
Indeed, the ip6_gre commit removed the local flag for collect_md
condition, so there is no reason to keep it for ip_gre/ip_tunnel.
this patch will fix both ip_tunnel and ip_gre modules.
Fixes: 2e15ea390e6f ("ip_gre: Add support to collect tunnel metadata.")
