====================
10GbE Intel Wired LAN Driver Updates 2017-02-16

This series contains updates to ixgbe only.

Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter
supports it.

Stephen Hemminger renames our dcbnl_ops since it is global to
ixgbe_dcbnl_ops to avoid namespace issues.

Mark updates the driver version based on the recent changes.

Alex has the remainder of the changes, starting with consolidating
functions that represent logical steps in the receive process so we can
later update them more easily (and align with igb).  Modify the receive
path to only synchronize the length of the frame versus the entire buffer.
Provided performance improvements by adding support for
DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING.  Also made additional
performance gains by batching the page count updates instead of doing
them one at a time.  Adjusted the receive path to use 3k buffers with
8k backing them in order to support build_skb with jumbo frames.  Made
additional driver improvements by using the length of the packet instead
of the DD status to determine if a new descriptor is ready to be
processed, which cuts down on reads.  To reduce code duplication, pulled
apart the receive path into separate functions.  Added support for
providing a buffer with headroom and tailroom to allow for shared info
for NET_SKB_PAD and NET_IP_ALIGN.
