====================
mlxsw: Add layer 3 devlink-trap support
This patch set from Amit adds support in mlxsw for layer 3 traps that
can report drops and exceptions via devlink-trap.
In a similar fashion to the existing layer 2 traps, these traps can send
packets to the CPU that were not routed as intended by the underlying
device.
The traps are divided between the two types detailed in devlink-trap
documentation: drops and exceptions. Unlike drops, packets received via
exception traps are also injected to the kernel's receive path, as they
are required for the correct functioning of the control plane. For
example, packets trapped due to TTL error must be injected to kernel's
receive path for traceroute to work properly.
Patch set overview:
Patch #1 adds the layer 3 drop traps to devlink along with their
documentation.
Patch #2 adds support for layer 3 drop traps in mlxsw.
Patches #3-#5 add selftests for layer 3 drop traps.
Patch #6 adds the layer 3 exception traps to devlink along with their
documentation.
Patches #7-#9 gradually add support for layer 3 exception traps in
mlxsw.
Patches #10-#12 add selftests for layer 3 exception traps.
