samples: pktgen: fix proc_cmd command result check logic
Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set. To cleanup pktgen on exit, trap has been added for EXIT signal. Signed-off-by:Daniel T. Lee <danieltimlee@gmail.com> Acked-by:
