The current implementation for mapping queues to vectors is broken because it attempts to map each Tx and Rx ring to its own vector, however we use combined queues so we should actually be mapping the Tx/Rx rings together on one vector. Also in the current implementation, in the case where we have more queues than vectors, we attempt to group the queues together into 'chunks' and map each 'chunk' of queues to a vector. Chunking them together would be more ideal if, and only if, we only had RSS because of the way the hashing algorithm works but in the case of a future patch that enables VF ADq, round robin assignment is better and still works with RSS. This patch resolves both those issues and simplifies the code needed to accomplish this. Instead of treating the case where we have more queues than vectors as special, if we notice our vector index is greater than vectors, reset the vector index to zero and continue mapping. This should ensure that in both cases, whether we have enough vectors for each queue or not, the queues get appropriately mapped.
