Description of PR
On certain servers we have seen the test_po_update_io_no_loss case failed because of excessive packet loss. The reason is the Arista VM couldn't receive the LACP update events from DUT due to cpu resource contention. Adding sleep(0) in the packet sending thread for a chance to yield CPU solved the problem.
