File 0001-ovs-ctl-Add-new-DPDK_OPTIONS-environment-variable.patch of Package openvswitch-dpdk.10750

Subject: [PATCH] ovs-ctl: Add new DPDK_OPTIONS environment variable

Add new DPDK_OPTIONS environment variable to hold the dpdk
vswitchd options so that the systemd unit files can be used to
launch an ovs-vswitcd DPDK capable instance instead of doing
it manually.

A similar patch has been submitted upstream
http://openvswitch.org/pipermail/dev/2016-July/074150.html
but got rejected because the master (2.6 at the time) has been
fixed in a different way and DPDK options are now part of the
ovsdb.
