Subject: [net-next 11/15] i40e/i40evf: Add txring_txq function to match fm10k and ixgbe
From: Alexander Duyck <alexander.h.duyck@...el.com>
This patch adds a txring_txq function which allows us to convert a
i40e_ring/i40evf_ring to a netdev_tx_queue structure. This way we
can avoid having to make a multi-line function call for all the spots
that need access to this.
