Merge branch 'net-cleanup-skb_tx_hash'
Alexander Duyck says:
====================
Clean up users of skb_tx_hash and __skb_tx_hash
I am in the process of doing some work to try and enable macvlan Tx queue
selection without using ndo_select_queue. As a part of that I will likely
need to make changes to skb_tx_hash. As such this is a clean up or refactor
of the two spots where he function has been used. In both cases it didn't
really seem like the function was being used correctly so I have updated
both code paths to not make use of the function.
My current development environment doesn't have an mlx4 or OPA vnic
available so the changes to those have been build tested only.
====================
