OVS 2.5.0 on Xenial, doesn't support its "options:n_rxq"...

[Christian Ehrhardt]

Hi Thiago,
everything all right here - just misreadable words.

I'll translate a bit:
Openvswitch <=2.5
ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=<queues_nr, the same
as QEMU>

Openvswitch >2.5
ovs-vsctl set Interface vhost-user1 options:n_rxq=<queues_nr, the same as
QEMU>

In Xenial we have Openvswitch 2.5 (there is no 2.6 yet and even 2.5 is just
a 6.5 weeks old).
So it is right that the first usage applies.
The more evolved is for OpenVswitch 2.6 whenever that will be
I also ran some tests with the first and it works for me.

Did the change from words to clear <=> signs help to clarify it?
