vdpa/mlx5: Re-create HW VQs under certain conditions
There are a few conditions under which the hardware VQs need a full
teardown and setup:
- VQ size changed to something else than default value. Hardware VQ size
modification is not supported.
- User turns off certain device features: mergeable buffers, checksum
virtio 1.0 compliance. In these cases, the TIR and RQT need to be
re-created.
Add a needs_teardown configuration variable and set it when detecting
the above scenarios. On next DRIVER_OK, the resources will be torn down
first.
