> 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.

Series applied, thanks Ido.
