Currently 10us delay is too low for many tests to succeed. It needs to
be increased. Also, many corked tests are expected to hit rx timeout
irrespective of timeout value.

- This patch sets 1000usec timeout value for corked tests because less
than that causes broken-pipe error in tx thread. Also sets 1 second
timeout for all other tests because less than that results in RX
timeout
- tests with apply=1 and higher number of iterations were taking lot
of time. This patch reduces test run time by reducing iterations.
