Basically, stop all moving parts before beginning to remove them. The current test-pmd quit is stopping and closing each device before moving to the next device. If all devices in the system are independent of each other, this difference is usually not important. In case of Soft NIC devices, any such virtual device typically depends on one or more physical devices being alive, as it accesses their queues, so this difference becomes important. Without this straightforward fix, all the Soft NIC devices need to be manually stopped before the quit command is issued, otherwise the quit command can sometimes crash the test-pmd application.
