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

[Martinx - ジェームズ]

Oh, I see! haha!   :-P

Thank you for your clarification!   >_<

BTW, too bad that DPDK 16.04 isn't on Ubuntu 16.04, I'm seeing that you
guys are backporting many, many fixes from 16.04, to 2.2... At least, I
hope that 16.07 will be available to Xenial via next Cloud Archive... It
looks very promising!

You guys are doing an impressive job on Ubuntu, congrats!

Cheers!
Thiago
