[dpdk-dev] [PATCH v2 3/4] net/virtio: fix segment data len in mergeable packed Rx path

[Maxime Coquelin]

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")
