====================
mlxsw: Introduce ACL traps

This patchset allows to track packets that are dropped in HW by ACL.

Unlike the existing mlxsw traps, ACL traps are "source traps".
That means the action is not controlled by HPKT register but directly
in ACL TRAP action. When devlink user changes action from drop to trap
and vice versa, it would be needed to go over all instances of ACL TRAP
action and do change. That does not scale. Instead, resolve this
by introducing "dummy" group with "thin" policer. The purpose of
this policer is to drop as many packets as possible. The ones
that pass through are going to be dropped in devlink code - patch #6
takes care of that.

First four patches are preparation for introduction of ACL traps in mlxsw
so it possible to easily change from drop to trap for source traps
as well - by changing group to "dummy" and back.

Merge branch 'mlxsw-Add-tunnel-devlink-trap-support'

Ido Schimmel says:

====================
mlxsw: Add tunnel devlink-trap support

This patch set from Amit adds support in mlxsw for tunnel traps and a
few additional layer 3 traps that can report drops and exceptions via
devlink-trap.

These traps allow the user to more quickly diagnose problems relating to
tunnel decapsulation errors, such as packet being too short to
decapsulate or a packet containing wrong GRE key in its GRE header.

Patch set overview:

Patches #1-#4 add three additional layer 3 traps. Two of which are
mlxsw-specific as they relate to hardware-specific errors. The patches
include documentation of each trap and selftests.

Patches #5-#8 are preparations. They ensure that the correct ECN bits
are set in the outer header during IPinIP encapsulation and that packets
with an invalid ECN combination in underlay and overlay are trapped to
the kernel and not decapsulated in hardware.

Patches #9-#15 add support for two tunnel related traps. Each trap is
documented and selftested using both VXLAN and IPinIP tunnels, if
applicable.

Merge branch 'devlink-documentation-refactor'

Jacob Keller says:

====================
devlink documentation refactor

This series updates the devlink documentation, with a few primary goals

* move all of the devlink documentation into a dedicated subfolder
* convert that documentation to the reStructuredText format
* merge driver-specific documentations into a single file per driver
* add missing documentation, including per-driver and devlink generally

For each driver, I took the time to review the code and add further
documentation on the various features it currently supports. Additionally, I
added new documentation files for some of the features such as
devlink-dpipe, devlink-resource, and devlink-regions.

Note for the region snapshot triggering, I kept that as a separate patch as
that is based on work that has not yet been merged to net-next, and may
change.

I also improved the existing documentation for devlink-info and
devlink-param by adding a bit more of an introduction when converting it to
the rst format.
