Lijuan, just one simple question. Why this suite choose 1,4,5,8,10 distributors, is there any logic related?

> +Packet Distributor
> +The DPDK Packet Distributor library is a library designed to be used for
> +dynamic load balancing of traffic while supporting single packet at a
> +time operation. When using this library, the logical cores in use are to
> +be considered in two roles: firstly a distributor lcore, which is
> +responsible for load balancing or distributing packets, and a set of
> +worker lcores which are responsible for receiving the packets from the
> +distributor and operating on them.
> +This is the test plan for Packet Distributor unit test.
> +This section explains how to run the unit tests for distributor.
> +The test can be launched independently using the command line interface.
> +This test is implemented as a linuxapp environment application.
> +The complete test suite is launched automatically using a python-expect
> +script (launched using ``make test``) that sends commands to
> +the application and checks the results. A test report is displayed on
> +The final output of the test will be average cycles of IO used per packet.
> +The steps to run the unit test manually are as follow::
> + # make -C ./app/test/
> + # ./app/test/test -n 1 -c ffff
