Reminder of this patch, waiting for minor updates, it would be good to have it 
before -rc1, so that the change can be tested thoroughly.

Meanwhile I have concern/question on long term testing of the feature. It is 
possible to break the multi-process support unintentionally and not recognize 
it. How can we continually verify the feature?

Are you using DTS?
Does it make sense to add a testcase into dts to test testpmd multi-process 
support so that it is verified on each release?
