The first patch fixes a virtio-spec violation. The other two patches
complete the driver configuration before using the VQs in the probe.

The patch order should simplify backporting in stable branches.

v2:
- patch 1 is not changed from v1
- added 2 patches to complete the driver configuration before using the
  VQs in the probe [MST]

v1: https://lore.kernel.org/netdev/20220322103823.83411-1-sgarzare@redhat.com/

Stefano Garzarella (3):
  vsock/virtio: enable VQs early on probe
  vsock/virtio: initialize vdev->priv before using VQs
  vsock/virtio: read the negotiated features before using VQs

Ok but I think the order is wrong. It should be 2-3-1,
otherwise bisect can pick just 1 and it will have
the issues previous reviw pointed out.

Right, I prioritized simplifying the backport, but obviously 
bisectability is priority!

I'll send v3 changing the order in 2-3-1

Thanks,
Stefano
