Subject: [dpdk-dev] [PATCH 1/2] net/af_xdp: enqueue buf ring when allocate Tx queue fails
Date: Fri, 12 Apr 2019 22:48:43 +0800 [thread overview]
Message-ID: <20190412144844.50712-1-xiaolong.ye@intel.com> (raw)
Message-ID: <20190412144843.qkiFEt8e5L_yKVItpN0LqsicmDYUGPppQIjlC7a8QTk@z> (raw)
In-Reply-To: <CAJFAV8y=fHuFWrbuH7fHB3kAHxiQMexmPSKvN+4v1nKVv3QAcg@mail.gmail.com>
When it fails to allocate enough slots in Tx queue for transmitting
packets, we need to return the dequeued addrs to buf ring.
Fixes: f1debd77efaf ("net/af_xdp: introduce AF_XDP PMD")
