"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs subsequently and while doing so, there is a chance that the rx one is not ready to accept socket connections. This racing bug could fail the test with at least one of the following:
./udpgso_bench_tx: connect: Connection refused ./udpgso_bench_tx: sendmsg: Connection refused ./udpgso_bench_tx: write: Connection refused
This change addresses this by making udpgro_bench.sh wait for the rx program to be ready before firing off the tx one - up to a 10s timeout.
