Subject: [PATCH 4.9 05/88] openvswitch: Add missing case OVS_TUNNEL_KEY_ATTR_PAD

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

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

From: Kris Murphy <kriskend@...ux.vnet.ibm.com>


[ Upstream commit 8f3dbfd79ed9ef9770305a7cc4e13dfd31ad2cd0 ]

Added a case for OVS_TUNNEL_KEY_ATTR_PAD to the switch statement
in ip_tun_from_nlattr in order to prevent the default case
returning an error.

Fixes: b46f6ded906e ("libnl: nla_put_be64(): align on a 64-bit area")
