      Description of problem:

       

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

      when running the latest rfc2544 on 4.14 nightly we got the following results (max delay is bad, other results are OK):

Version	OCP Version				Frame size	Throughput	Min Delay	Avg Delay	Max Delay	NIC	Cluster	Duration	Kernel
4.14	4.14.0-0.nightly-2023-07-16-230237	512		99.883		5.79		7.388		84.21		e810	cnfde4	8h		5.14.0-284.23.1.rt14.308.el9_2.x86_64

       

      How reproducible:

      always

      Steps to Reproduce:

      1.deploy the latest 4.14 nightly on cnfde4
2. run the rfc2544 test
3.

      Actual results:

      Throughput	Min Delay	Avg Delay	Max Delay
99.883		5.79		7.388		84.21

      Expected results:

      max delay should be around 40
