Description Christophe Fontaine 2023-07-24 12:58:14 UTC 
OVS-DPDK has a new option to enter "sleep" mode when no packets has to be forwarded.
We need to ensure this introduces:
- neither a significant performance regression at a high packet rate
- nor a significant latency increase with few packets/s.
