They are offloaded to the application (examples/vhost/vhost-switch in
this case).
user_destroy_device will invoke the application's "destroy_device()"
callback in the end, which, in our case, will set "remove" flag. The
core worker will then drain and free the RX queue and free TX queue
once the "remove" flag is set.
