[dpdk-dev] [PATCH v2 1/9] net/virtio: fix rewriting LSC flag

[Jianfeng Tan]

The LSC flag is decided according to if VIRTIO_NET_F_STATUS feature
is negotiated. Copy the PCI info after the judgement will rewrite
the correct result.

Fixes: 198ab33677c9 ("net/virtio: move device initialization in a function")
