functional test 6 : use several queues (each with its own run-time data),
            use several RED configurations (such that each
configuration is sharte_red by multiple queues),
            increase average queue size to target level,
            dequeue all packets until queue is empty,
            confirm that average queue size is computed correctly
while queue is empty
            (this is a larger scale version of functional test 3)

queue          config         q avg before   q avg after    expected
    difference %   tolerance %    result
0              0              1022.0000      1022.0000      1016.0627

This failure keeps on popping in the CI.
The bug report is one month old, with no reply.


I sent a proposal of removing red_autotest from the list executed by the CI.
https://patchwork.dpdk.org/project/dpdk/patch/20211027140458.2502-2-david.marchand@redhat.com/

It might be the best solution waiting for an analysis.
