====================
40GbE Intel Wired LAN Driver Updates 2017-10-06

This series contains updates to i40e and i40evf only.

Rami fixes a typo in the code comments.

Mitch adds an ethtool private flag to control source pruning to resolve an
issue where our default behavior is to enable source pruning which breaks ARP
monitoring in channel bonding.  Fixes a couple of register definitions, which
were incorrect.

Jake fixes an issue with multiple logical CPUs per core (simultaneous
multithreading - SMT) and how we set an affinity hint based on the v_idx of
that q_vector, which is an incremental value and might lead to multiple
offline CPUs being assigned to a q_vector.  Instead, we should only assign
hints for CPUs which are online, so look to use cpumask_local_spread().
Also fixed a VF VLAN tag stripping issue, where the flag created to change
this feature was seen as unchangeable.  Lastly, organized and re-numbered
the feature flags.

Alan re-enables PTP L4 for XL710 devices with firmware version 6.0 or
greater, now that the previous bug in the older firmware is fixed.
Implements the PCI error handlers for reset_prepare() and reset_done() to
allow us to handle function level resets.

Alice cleans up code that was added to the incorrect function during a
merge.

Filip adds a change to display an error message when a module is inserted
that does not meet the thermal requirements, Talking Heads "Burning Down
the House" comes to mind.  Also fixed a flow director filter issue where
a variable was not being cleared which stores the filter number to be
removed from the list when the firmware refused to add the requested
filter.
