Merge branch 'ixgbevf'

Aaron Brown says:

====================
Intel Wired LAN Driver Updates

This series contains updates from Emil to ixgbevf.

He cleans up the code by removing the adapter structure as a
parameter from multiple functions in favor of using the ixgbevf_ring
structure and moves hot-path specific statistic int the ring
structure for anticipated performance gains.

He also removes the Tx/Rx counters for checksum offload and adds
counters for tx_restart_queue and tx_timeout_count.

Next he makes it so that the first tx_buffer structure acts as a
central storage location for most the skb info we are about to
transmit, then takes advantage of the dma buffer always being
present in the first descriptor and mapped as single allowing a
call to dma_unmap_single which alleviates the need to check for
DMA mapping in ixgbevf_clean_tx_irq().

Finally he merges the ixgbevf_tx_map call and the ixgbevf_tx_queue
call into a single function.
