ODP basic queue test
Added odp_queue_test.c to show a failing test case where ODP ordered queues
deadlock. This test was hacked together from various files and has not been
throuroughly tested, but it should showcase the faulty behaviour.
Usage:
$> odp_queue_test --help
Usage: odp_queue_test APPL-OPTIONS
E.g. odp_queue_test -c 0xf -t
Open Data Plane example application.
Mandatory OPTIONS:
-c, --coremask Select the cores to use, hexadecimal
-p, --process-per-core Running ODP with one process per core.
-t, --thread-per-core Running ODP with one thread per core.
Select EITHER -p OR -t, but not both!
Optional [APPL-OPTIONS]
-h, --help Display help and exit.
To see the error run on one core vs e.g 2 cores:
1 core:
test-Q:98: type:parallel 1 events | Core01: 1 events
| this event scheduled: 1 times
test-Q:99: type:ordered 1 events | Core01: 5 events

... continue forever ...
2 cores:
$> odp_queue_test -c 0x3 -t
Entering the event dispatch loop(forever=0) on core 1
Entering the event dispatch loop(forever=0) on core 2
