One new cmdline option `--rx-mq-mode` is added in order to have the
possibility to check whether PMD handle the mq mode correctly or not.
The reason is some NICs need to do different settings based on different
RX mq mode, i.e RSS or not.
With this support in testpmd, the above scenario can be tested easily.
