Subject: [dpdk-dev] [PATCH v3] net/vhost: fix segfault when creating vdev
dynamically
When creating vdev dynamically, vhost pmd driver starts directly without
checking TX/RX queues are ready or not, and thus causes segmentation fault
when vhost library accesses queues. This patch adds a flag to check whether
queues are setup or not, and adds queues setup into dev_start function to
allow user to start them after setting up.
Fixes: aed0b12930b3 ("net/vhost: fix socket file deleted on stop")

Thanks for Junjie's patch!
I also came across the similar issue when developing virtio-user server mode.
From user's perspective, the patch can fix the issue in my user case instead of
the patch http://www.dpdk.org/dev/patchwork/patch/36340/
