Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-05-02

This series contains updates to the ice driver only.

Anirudh introduces the framework to store queue specific information in
the VSI queue contexts.  This will allow future changes to update the
structure to hold queue specific information.

Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock.  Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.

Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.

Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue.  Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability.  Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value.  Found we had
unnecessary wait when disabling queues, so remove it.  I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index.  Refactored the link event
flow to make it cleaner and more clear.

Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.

Paul adds support for setting 52 byte RSS hash keys.

Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.

Tony adds a missing PHY type, which was causing warning message about an
unrecognized PHY.
