On Scale testbed there are 2 main differences:

  1. There are much more PTF ports(512)
  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, and with more timeouts, the function verify_packet would capture the packet.

hi Chuan - do you mind to update the PR description on how this PR is fixing the issue? also is this a cherry pick PR from any PR in master?
