The default values of rx mq_mode and rx offloads for port
will cause symmetric_mp startup failure if the port do
not support rss or csum. Therefore, we added two new options
--rx-mq-mode and --rx-offloads, through which the user can set
the values appropriately according to the situation to make
app startup normally.
