Since wlantest is a separate process that is not synchronized with rest of the test components, there can be some latency in it having the STA entries and counters updated. There is a race condition between this happening and then test script clearing or fetching data. Make this race condition less likely to cause bogus test failures by adding some wait between these operations. Signed-hostap: Jouni Malinen <j@w1.fi>
