Function test_pflock

dpdk/app/test/test_pflock.c:160–194

* - There is a global pflock and a table of pflocks (one per lcore). * * - The test function takes all of these locks and launches the * ``test_pflock_per_core()`` function on each core (except the main). * * - The function takes the global write lock, display something, * then releases the global lock. * - Then, it takes the per-lcore write lock, display something, and * rel

 *   message. The autotest script checks that the message order is correct.
