Hi Luca,

I created a Bugzilla ticket to track the issues with Multi-Packet Rx queue (mprq). We hope to resolve it in 20.11.10:

https://bugs.dpdk.org/show_bug.cgi?id=1274 - [20.11 LTS] Multi-Packet Rx queue parameters are incorrectly adjusted and not applied properly

We're ok to release.

Thanks,
Ali
