[PATCH v2] bus/vmbus: add device_order field to rte_vmbus_dev

[Vladimir Ratnikov]

Field can be used to have static interface naming
in DPDK based applications instead of uuid.
RTE_FOREACH_DEV won't return the correct order of
such devices due to vmbus_ignore_device in case of
blocklisting/allowlisting. So device_order field
will be helpful in that case.
