* rte_atomic32_inc_and_test() would increase a 32 bits counter by one and then * test if that counter is equal to 0. It would return true if the counter is 0 * and false if the counter is not 0. rte_atomic64_inc_and_test() could do the * same thing but for a 64 bits counter. * Here checks that if the 32/64 bits counter is equal to 0 after being atomically * increased by one. If it is, increas
