Subject: [dpdk-dev] [PATCH v2 3/4] net/virtio: fix segment data len in mergeable packed Rx path
Date: Wed,  5 Jun 2019 10:10:04 +0200	[thread overview]
Message-ID: <20190605081005.15716-4-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20190605081005.15716-1-maxime.coquelin@redhat.com>

Head segment data_len field is wrongly summed with the length
of all the segments of the chain, whereas it should be the
length of of the first segment only.

Fixes: a76290c8f1cf ("net/virtio: implement Rx path for packed queues")
Cc: stable@dpdk.org
