It is a little confused. Is the cfgfile-path is application's argument or EAL's?
Where is it supposed to be located?

Does it mean if RTE_LIBRTE_CFGFILE is defined, then the arguments are passed by
Cfgfile, if no cfgfile will use config.ini by default? How about the legacy command lines?
I think even cfgfile is good, we still need to keep the command line way.

The argc and argv have been overwritten by cfgfile, right? Does it make sense to
Pass cfg to  launch_args_parse?


And you also need to update the testpmd doc to describe this new use.

Thanks
