* When you run Cloud-native Network Functions (CNF) latency tests on an {product-title} cluster, the test can sometimes return results greater than the latency threshold for the test; for example, 20 microseconds for `cyclictest` testing. This results in a test failure.

Description of problem:


KPI runs of RFC2544 KPI on SNO cluster deployed with Telco RAN DU profile
reports latencies above 30

e.g 35.645µs

Version-Release number of selected component (if applicable):

OCP 4.17.0 up through rc.3
but also present in OCP 4.16.0-rc.9

How reproducible:

always

Steps to Reproduce:

    1. Deploy 4.17 on SNO cluster and apply Telco RAN DU profile
    2. Run rfc2544=12h test
    3. Observe results

Actual results:

Reported max latency >= 30µs

Expected results:

Reported max latency < 30µs

Additional info:

must-gather, etc. will be added in a comment. Oirignal environment is not
avaialble, so I will run on 4.17.0-rc.7 and gather logs at that point.
