If there is nothing specific in DPDK for PQos, why writing an example in
DPDK?

The example makes it much easier to use the technology with DPDK.

Maybe the example should be better in the library itself.

The library in question (https://github.com/01org/intel-cmt-cat) has a couple of examples but none of them refers to DPDK.

I suggest to mention the library in
doc/guides/linux_gsg/nic_perf_intel_platform.rst

Ok it can be added to this document. Does it imply -1 for the sample code idea?

I may be wrong but I have the feeling the example is more about PQoS than DPDK.
So yes, I would vote -1.

Well, the intersection of DPDK and PQoS is what the example is really all about,
and as such it is relevant to both DPDK and the library itself. Platform QoS
can be of great use to packet processing applications for helping to ensure that
the app gets the resources it needed - especially in a virtualised world - and
so we believe that having an example in DPDK showing how to use PQoS with DPDK
is well worthwhile having. It's more effective than a simple doc update in
raising awareness of the existence of the feature, and also provides for DPDK
users a readily available app for the user to start playing with to evaluate
PQoS for their own use-cases.

+1 
I also think it is a good thing to have.
Again user don't have to trust the whitepapers - instead he can run the app 
and measure performance gain on his particular platform.

I also fail to see what the downside of having the sample app is - it won't add
significantly to the project maintenance overhead.
