Subject: [dpdk-dev] [PATCH v2] sched: fix releasing enqueued packets
Date: Tue, 6 Sep 2016 00:15:14 +0900 [thread overview]
Message-ID: <1473088514-31836-1-git-send-email-h.mikita89@gmail.com> (raw)
In-Reply-To: <1472699482-1747-1-git-send-email-h.mikita89@gmail.com>
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")
Signed-off-by: Hiroyuki Mikita <h.mikita89@gmail.com>

v2:
* use rte_sched_port_queues_per_port to get the number of queues
* mask incremented qr by qsize - 1
