Hi Connor,

For people new to dpdk/test-pmd, it may be hard to figure out these two
parameter is related to multi-process support. What do you think updating
the description to clarify these are for multi-process support?

+1 not just for this but in general.
Group them and add a comment.
Or add that in the help text.

[PATCH v4] app/testpmd: add help messages for multi-process

[Min Hu (Connor)]

From: Huisong Li <lihuisong@huawei.com>

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.

Why not reusing these defines?

#define PARAM_PROC_ID "proc-id"
#define PARAM_NUM_PROCS "num-procs"

Why not having "N" in the help messages like others?

I won't pull it in main.
Please rework and try to improve the description to make it shorter
and easier to understand.

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?

Hi Connor,

output is as following [1], is "(0 <= id < num-procs)." part break into 
next line intentionally? This breaks the output.

I assume the line is broken in source code to fit into line length, but 
it doesn't have to break the line in output, what do you think?


[1]
...
   --num-procs=N: set the total number of multi-process instances
   --proc-id=id:  set the id of the current process from multi-process ..
(0 <= id < num-procs).
   --nb-cores=N: set the number of forwarding cores (1 <= N <= 55).
...

there are double space after '--proc-id=id:', but I can fix it while 
merging.
