From: Boris Sukholitko <boris.sukholitko@xxxxxxxxxxxx> When running nft_flowtable.sh in VM on a busy server we've found that the time of the netcat file transfers vary wildly. Therefore replace hardcoded 3 second sleep with the loop checking for a change in the file sizes. Once no change in detected we test the results. Nice side effect is that we shave 1 second sleep in the fast case (hard-coded 3 second sleep vs two 1 second sleeps).
