Description of PR

On Scale testbed there are 2 main differences:

  1. There are much more PTF ports
  2. There are much more OVS and interface configurations

Those lead to:

  1. NIC would take more time to handle the receiving packets
  2. PTF could take more time to process

As a result:

  1. More time to spend in ptf function testutils.verify_packet

Summary:
Fixes # (issue)

Type of change

  • Bug fix
  • Testbed and Framework(new/improvement)
  • New Test case
    • Skipped for non-supported platforms
  • Test case improvement

Back port request

Approach

What is the motivation for this PR?

To increase the PTF traffic handling stability in the scale testbed

How did you do it?

Add more wait time in ptf function testutils.verify_packet

How did you verify/test it?

Run it in the local scale testbed

Any platform specific information?

Supported testbed topology if it's a new test case?
