Well, we have our own DTS system which contains testcase of multiple
process in testpmd:
1. When we upstream patches to DPDK，the patch should pass all the testcase.
2. Before DPDK version release(in RC1) in every three months, we rebase
the new DPDK version, and check all the testcase in our DTS system. If
some testcase fails, we will fix it and upstream the patch to DPDK, of
course, including multi-process support in testpmd.
