Public bug reported:
The test configures a meter 10pps meter, then rapidly transmits 40
packets with Scapy, and checks that a specific amount of drops is sent,
10.
For some reason the test fails on arm64 because unexpectedly(?) 11 drops
are sent instead of 10.
Instrumenting the test to capture all packets it looks like this:

Not sure if this is a defect in the product or the test but the

there.
