[3/8] examples/packet_ordering: enhance getopt_long usage
Checks
Commit Message
Instead of using getopt_long return value, strcmp was used to
compare the input parameters with the struct option array. This
patch get rid of all those strcmp by directly binding each longopt
with an int enum.
Bugzilla ID: 238
Fixes: 850f3733f8 ("examples/packet_ordering: new sample app")
Fixes: 016493307a ("examples/packet_ordering: add stats per worker thread")
