    Description

      rca: 
         test: 100b tcp tput
         frequency: all
         testbed: 2n-clx, 2n-icx, 2n-skx

      example:

      This is with TRex v2.97 (and using reset).
      Does not affect UDP tests.
      Does not happen on 2n-dnv, does happen on 2n-skx and 2n-clx.
      The error happens on client.stop() call (with or without block=False) so it affects both synchronous and asynchronous stop, but the exact symptom looks different.
      Transaction scale does not seem to matter.

      More investigations are in progress.
