Subject: [dpdk-stable] [PATCH v2 2/4] net/virtio: fix memory leak in mergeable Rx
Date: Thu, 20 Jun 2019 10:34:34 +0800 [thread overview]
Message-ID: <20190620023436.12819-3-tiwei.bie@intel.com> (raw)
In-Reply-To: <20190620023436.12819-1-tiwei.bie@intel.com>
When there is no enough segments for a packet in mergeable
Rx path, we should free the whole mbuf chain instead of just
recycling the last segment.
Fixes: bcac5aa207f8 ("net/virtio: improve batching in mergeable path")
