As I known 82599 support 16 queues, not sure about other NICs and not
every NIC has more than 15 queues.
Queue requirement may not fulfilled on some 1G cards. Its' better to
choice max queue supported by NIC type.

Just send one packet can not verify that every queue waked up. And we
need to verify not only core but also queue information is correct.
