Subject: [PATCH AUTOSEL for 4.9 089/293] ip6_tunnel: Correct tos value in
 collect_md mode

From: Haishuang Yan <yanhaishuang@...s.chinamobile.com>

[ Upstream commit 46f8cd9d2fc1e4e8b82b53a0007f6c92e80c930b ]

Same as ip_gre, geneve and vxlan, use key->tos as traffic class value.

Fixes: 0e9a709560db ("ip6_tunnel, ip6_gre: fix setting of DSCP on
encapsulated packets”)
