Subject: [PATCH 4.4 03/28] [PATCH 05/41] vti6: return GRE_KEY for vti6

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Forster <dforster@...cade.com>

[ Upstream commit 7dcdf941cdc96692ab99fd790c8cc68945514851 ]

Align vti6 with vti by returning GRE_KEY flag. This enables iproute2
to display tunnel keys on "ip -6 tunnel show"
