This patch adds help messages for multi-process.
--num-procs <N>, where N is the total number of symmetric_mp instances
that will be run side-by-side to perform packet processing. This parameter
is used to configure the appropriate number of receive queues on each
network port.
--proc-id <n>, where n is a numeric value in the range 0 <= n < N (number
of processes, specified above). This identifies which symmetric_mp instance
is being run, so that each process can read a unique receive queue on each
network port.

I am not exactly sure what is 'symmetric' in 'symmetric_mp' here,
there is a sample application with this name but I guess 'symmetric'
is related to that sample functionality.
Would you mind if I change 'symmetric_mp' with 'multi-process'
while applying?
