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

[Martinx - ジェームズ]

Hey guys,

 I'm curious about something, at the QEmu Wiki (
http://wiki.qemu.org/Features/vhost-user-ovs-dpdk) page, we have this info:

---
Enabling multi-queue
Enable multi-queue

   - OVS setup

In OVS 2.5.0 or older version: (It only supports setting up same
number of rx queues for all of PMD netdevs.)
    ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=<queues_nr,
the same as QEMU>
    ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=<cpu mask
for rx queues, say 0xff00>

In post OVS 2.5.0:
    ovs-vsctl set Interface vhost-user1 options:n_rxq=<queues_nr, the
same as QEMU>
    ovs-vsctl set Interface vhost-user2 options:n_rxq=<queues_nr, the
same as QEMU>
    ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=<cpu mask
for rx queues, say 0xff00>



---

However, OpenvSwitch 2.5.0 available on Xenial, does not support
"options:n_rxq", like the second above example... It says that this option
isn't available and multiqueue doesn't get enabled, while the first options
works...

Looks like that the second option is more evolved... Am I missing something
here?

Cheers!
Thiago
