#1319253 — [PATCH 4.3 083/157] openvswitch: correct encoding of set tunnel action attributes

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

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

From: Simon Horman <simon.horman@netronome.com>

[ Upstream commit e905eabc90a5b787d8708df164543ee295bea5f2 ]

In a set action tunnel attributes should be encoded in a
nested action.

I noticed this because ovs-dpctl was reporting an error
when dumping flows due to the incorrect encoding of tunnel attributes
in a set action.
