"""
The variable optind is the index of the next element to be processed in
argv. The system initializes this value to 1. The caller can reset it
to 1 to restart scanning of the same argv, or when scanning a new
argument vector.
"""
Hence, if an invalid option is passed through testpmd cmdline, getopt
returns '?' and increments optind to the next index in argv for a
subsequent call.
The message should log the previous index.
