====================
40GbE Intel Wired LAN Driver Updates 2016-12-07

This series contains updates to i40e and i40evf only.

Filip modifies the i40e to log link speed change and when the link is
brought up and down.

Mitch replaces i40e_txd_use_count() with a new function which is slightly
faster and better documented so the dim witted can better follow the
code.  Fixes the locking of the service task so that it is actually
done in the service task and not in the scheduling function which calls
the service task.

Jacob, being the busy little beaver he is, provides most of the changes
starting restores a workaround that is still needed in some configurations,
specifically the Ethernet Controller XL710 for 40GbE QSFP+.  Removes
duplicate code and simplifies the i40e_vsi_add_vlan() and
i40e_vsi_kill_vlan() functions.  Removes detection of PTP frames over L4
(UDP) on the XL710 MAC, since there was a product decision to defeature
it.  Fixed a previous refactor of active filters which caused issues in
the accounting of active_filters.  Remaining work was done in the VLAN
filters to improve readability and simplify code as much as possible
to reduce inconsistencies.

Alex fixes foul budget accounting in core code by returning actual
work done, capped to budget-1.

Henry fixes the "ethtool -p" function for 1G BaseT PHYs.

Carolyn adds support for 25G devices for i40e and i40evf.

Michal adds functions to apply the correct access method for external PHYs
which could use Clause22 or Clause45 depending on the PHY.

v2: dropped last patch from previous series, since changes are needed based
    on feedback from Sergei Shtylyov
