====================
10GbE Intel Wired LAN Driver Updates 2018-02-26

This series contains updates to ixgbe and ixgbevf only.

Colin Ian King cleans up redundant variable assignments.

Tonghao Zhang updates ixgbe to avoid writing to the hardware when the
redirection table has not changed.

Jake fixes the driver logic for checking and clearing receive timestamp
hangs so that when the PTP_RX_TIMESTAMP_IN_REGISTER flag is set, we no
longer need to check for receive timestamp hangs, which in turn will
stop the spurious log messages.

Emil updates ixgbevf with several features and improvements done in
other drivers, starting with the handling of page addresses so that we
always refer to them using a void pointer.  Added a 'legacy-rx' flag to
allow switching between the old and new receive code paths.  Added
support for using 3K buggers in order 1 page.  Updated the driver to
ensure that calls to ixgbevf_open() are rtnl lock protected and improved
the error handling when setting up multiple queues.  Added support for
providing a buffer with head room and tail room to allow for shared
info, NET_SKB_PAD, and NET_IP_ALIGN, so that we can start using
build_skb to build frames instead of using memcpy() the headers.
Updated the logic of handling rings closer to ixgbe.  Consolidated the
receive paths to reduce duplication when we expand them in the future.
Added build_skb() support to ixgbevf.
