Traffic is not offloaded

OVS uses TC flower classifier to add offloading rules to both the software and the hardware.

  • TC flower classifier fails to add a rule.
  • A rule was added to the TC flower classifier but failed to be added to the firmware.
  • Check for system error in dmesg or the system logging facility like journalctl
  • Check OVS logs for errors
  • Dump the rules using the TC command line
    For example: Dump rules on a specific interface
    # tc filter show dev ens4f0 parent ffff:
