[dpdk-dev] virtio-net: bind systematically on all non blacklisted virtio-net devices

Hi, virtio-net driver bind on all virtio-net devices, even if the devices are used by the kernel (leading to kernel soft-lookup/panic). One way around is to blacklist the ports in use by Linux. This is the case since v2.0.0, in fact since commit da978dfdc43b59e290a46d7ece5fd19ce79a1162 and the

[dpdk-dev] Wrong TCP checksum of packets sent by Linux guest (virtIO/vhost)

Hello, This is a repost of https://lists.01.org/pipermail/dpdk-ovs/2014-September/001788.html as the issue might be related to dpdk.org vhost code. I am using dpdk-ovs 1.1.0 (latest release) as follow : linux-guest (no DPKD) <--- virtIO ---> OVDK 1.1.0 (with latest DPDK [*]) < --- Niantic --
