There is no need for a feature bit for something that
can be tested by simply checking the TX queue count.

-Finally, the base driver should indicate that it is a multiqueue device. The
-feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features
-bitmap on device initialization. Below is an example from e1000:
