Hi,
FYI, your patch has been queued to stable release 16.07.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable

So please shutout if anyone has objections.
Thanks.

Subject: [PATCH] sched: fix releasing enqueued packets
[ upstream commit 7b3c4f351708a4bf5d311266d9f8c32e5704701f ]
rte_sched_port_free should release only enqueued packets of all queues.
Previous behavior is that enqueued and already dequeued packets of
only first 4 queues are released.
Fixes: 61383240 ("sched: release enqueued mbufs when freeing port")
