[PATCH RFC 0/3] Support live migration with mlx5_vdpa

Following patchset supports the suspend callback to suspend VQs to allow
sshdow VQs to kick in. It also adds address space support also required
for live migration. We use two groups, one for the control virtqueue and
one for the data virtqueues.

Finally there is a patch that disables VLAN support since it is not
supported currently.

The aim of this patchset is to allow enable development/testing of live
migration over a real hardware device.

The below two patches are also required to be applied but I did not
include them in the series since they were sent separately.
