Jeff Kirsher says:

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

This series contains updates to i40e and i40evf.

Shannon makes minor changes to the AdminQ interface to bring it up to
date.  Removes the hard coding of stats struct size in ethtool, in prep
for adding data fields which are configuration dependent.

Catherine removes some unused and unneeded PCI bus defines.

Jesse fixes the copyright headers and finishes up the removal of the PTP
Tx work functionality which allows us to rely on the Tx timesync interrupt.

Mitch provides a number of fixes and cleanups for i40e/i40evf based on
suggestions from Ben Hutchings.  First is to use a macro parameter for
ethtool stats instead of just assuming that a valid netdev variable
exists.  Second is not to tell ethtool that the VF can do 10GbaseT, when
it really has no idea what its link speed is, so set the supported value
to 0 instead.  Make the ethtool_ops structure constant since it is
extremely unlikely to change at runtime.  Ethtool consistently reports
0 values for our ITR settings because we never actually use them, so
fix this by setting the default values to the specified default values.

Greg avoids a compile error by wrapping the call to i40e_alloc_vfs() in
CONFIG_PCI_IOV because the function itself is wrapped in the same
conditional compile block.

Alexander Gordeev updates the driver to use the new pci_enable_msi_range()
and pci_enable_msix_range() or pci_enable_msi_exact() and
pci_enable_msix_exact().

Jean Sacren provides a fix where the wrong error code was being passed to
i40e_open().
