[Bug 2060941] Re: [ovn 22.03][arm64] ovn -- CoPP test fails

2024-04-11 Thread Frode Nordahl 
** Description changed:

- 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.
+ The test configures a 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:
- # cat all.pcap 
+ # cat all.pcap
