Currently, we only check the latest senders's exit code. If the receiver
report failed, it is not recoreded. Fix it by checking the exit code
of all the involved processes.
Before:
bad GRO lookup ok
multiple GRO socks ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
failed
$ echo $?
0
After:
bad GRO lookup ok
multiple GRO socks ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
failed
$ echo $?
