Commit Message

Tushar Vyavahare July 2, 2024, 5:59 a.m. UTC 
Previously, HW_SW_MIN_RING_SIZE and HW_SW_MAX_RING_SIZE test cases were
not validating Tx/Rx traffic at all due to early return after changing HW
ring size in testapp_validate_traffic().

Fix the flow by checking return value of set_ring_size() and act upon it
rather than terminating the test case there.
