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 2020-05-21

This series contains updates to ice driver only.  Several of the changes
are fixes, which could be backported to stable, of which, only one was
marked for stable because of the memory leak potential.

Jake exposes the information in the flash memory used for link
management, which is called the netlist module.

Henry and Tony add support for tunnel offloads.

Brett adds promiscuous support in VF's which is based on VF trust and
the new vf-true-promisc flag.

Avinash fixes an issue where a transmit timeout for a queue that belongs
to a PFC enabled TC is not a true transmit timeout, but because the PFC
is in action.

Dave fixes the check for contiguous TCs to allow for various UP2TC
mapping configurations.  Also fixed an issue when changing the pause
parameters would could multiple link drop/down's in succession, which in
turn caused the firmware to not generate a link interrupt for the driver
to respond to.

Anirudh (Ani) fixed a potential race condition in probe/open due to a
bit being cleared too early.

Lihong updates an error message to make it more meaningful instead of
just printing out the numerical value of the status/error code.  Also
fixed an incorrect return value if deleting a filter does not find a
match to delete or when adding a filter that already exists.

Karol fixes casting issues and precision loss in the driver.

Jesse make the sign usage more consistent in the driver by making sure
all instances of vf_id are unsigned, since it can never be negative.

Eric fixes a potential memory leak in ice_add_prof_id_vsig() where was
not cleaning up resources properly when an error occurs.

Michal to help organize the filtering code in the driver, refactor the
code into a separate file and add functions to prepare the filter
information.

Bruce cleaned up a conditional statement that always resulted in true
and provided a comment to make it more obvious.  Also cleaned up
redundant code checks.

Tony helps with potential namespace issues by renaming a 'ice' specific
function with the driver name prepended.
