Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-08-26

This series contains updates to ice driver only.

Usha fixes the statistics reported on 4 port NICs which were reporting
the incorrect statistics due to using the incorrect port identifier.

Victor fixes an issue when trying to traverse to the first node of a
requested layer by adding a sibling head pointer for each layer per
traffic class.

Anirudh cleans up the locking and logic for enabling and disabling
VSI's to make it more consistent.  Updates the driver to do dynamic
allocation of queue management bitmaps and arrays, rather than
statically allocating them which consumes more memory than required.
Refactor the logic in ice_ena_msix_range() for clarity and add
additional checks for when requested resources exceed what is available.

Jesse updates the debugging print statements to make it more useful when
dealing with link and PHY related issues.

Krzysztof adds a local variable to the VSI rebuild path to improve
readability.

Akeem limits the reporting of MDD events from VFs so that the kernel
log is not clogged up with MDD events which are duplicate or potentially
false positives.  Fixed a reset issue that would result in the system
getting into a state that could only be resolved by a reboot by
testing if the VF is in a disabled state during a reset.

Michal adds a check to avoid trying to access memory that has not be
allocated by checking the number of queue pairs.

Jake fixes a static analysis warning due to a cast of a u8 to unsigned
long, so just update ice_is_tc_ena() to take a unsigned long so that a
cast is not necessary.

Colin Ian King fixes a potential infinite loop where a u8 is being
compared to an int.

Maciej refactors the queue handling functions that work on queue arrays
so that the logic can be done for a single queue.

Paul adds support for VFs to enable and disable single queues.

Henry fixed the order of operations in ice_remove() which was trying to
use adminq operations that were already disabled.
