====================
100GbE Intel Wired LAN Driver Updates 2019-02-22

This series contains updates to the ice driver only.

Bruce adds the __always_unused attribute to a parameter to avoid
compiler warnings when using -Wunused-parameter.  Fixed unnecessary
type-casting and the use of sizeof().  Fix the allocation of structs
that have become memory hogs, so allocate them in heaps and fix all the
associated references.  Fixed the "possible" numeric overflow issues
that were caught with static analysis.

Maciej fixes the maximum MTU calculation by taking into account double
VLAN tagging amd ensure that the operations are done in the correct
order.

Victor fixes the supported node calculation, where we were not taking
into account if there is space to add the new VSI or intermediate node
above that layer, then it is not required to continue the calculation.
Added a check for a leaf node presence for a given VSI, which is needed
before removing a VSI.

Jake fixes an issue where the VSI list is shared, so simply removing a
VSI from the list will cause issues for the other users who reference
the list.  Since we also free the memory, this could lead to
segmentation faults.

Brett fixes an issue where driver unload could cause a system reboot
when intel_iommu=on parameter is set.  The issue is that we are not
clearing the CAUSE_ENA bit for the appropriate control queues register
when freeing the miscellaneous interrupt vector.

Mitch is so kind, he prevented spamming the VF with link messages when
the link status really has not changed.  Updates the driver to use the
absolute vector ID and not the per-PF vector ID for the VF MSIx vector
allocation.

Lukasz fixes the ethtool pause parameter for the ice driver, which was
originally based off the link status but is now based off the PHY
configuration.  This is to resolve an issue where pause parameters could
be set while link was down.

Jesse updates the string that reports statistics so the string does not
get modified at runtime and cause reports of string truncation.
