      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.
