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

From: Greg Kroah-Hartman
Date: Wed Jan 27 2016 - 13:24:35 EST

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


From: Simon Horman <simon.horman@xxxxxxxxxxxxx>

[ 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.

Fixes: fc4099f17240 ("openvswitch: Fix egress tunnel info.")
