Description OvS team 2023-01-09 14:38:17 UTC 
+++ This bug was initially created as a clone of Bug #1776816 +++

Description of problem:
By default, the OVS datapath packet counter is set 10 digits.

During offload performance test with 53Mpps, we noticed OVS offload datapath flow statistics get over-run within 100sec and maximum reach out ~53000000 packet counters.
We would expect the packet counter reach to at least 9999999999 before reset. Also, need to think on ideal size of counter digits when it is running over 100 gig bandwidth nic.


Version-Release number of selected component (if applicable):
	Red Hat OpenStack Platform release 13.0.9 (Queens)
	Red Hat Enterprise Linux Server release 7.7 (Maipo)
	openstack-neutron-openvswitch-12.1.0-2.el7ost.noarch
	openvswitch2.11-2.11.0-26.el7fdp.x86_64
	openvswitch2.11-test-2.11.0-26.el7fdp.noarch
	python-openvswitch2.11-2.11.0-26.el7fdp.x86_64

How reproducible:
100% reproducible in the lab.


Steps to Reproduce:
  # ovs-dpctl dump-flows -m type=offloaded
