DESCRIPTION

   devlink trap show - display available packet traps and their attributes
       DEV - specifies the devlink device from which to show packet traps.  If this argument is
       omitted all packet traps of all devices are listed.

       trap TRAP - specifies the packet trap.  Only applicable if a devlink device is also
       specified.

   devlink trap set - set attributes of a packet trap
       DEV - specifies the devlink device the packet trap belongs to.

       trap TRAP - specifies the packet trap.

       action { trap | drop | mirror }
              packet trap action.

              trap - the sole copy of the packet is sent to the CPU.

              drop - the packet is dropped by the underlying device and a copy is not sent to the
              CPU.

              mirror - the packet is forwarded by the underlying device and a copy is sent to the
              CPU.

   devlink trap group show - display available packet trap groups and their attributes
       DEV - specifies the devlink device from which to show packet trap groups.  If this
       argument is omitted all packet trap groups of all devices are listed.

       group GROUP - specifies the packet trap group.  Only applicable if a devlink device is
       also specified.

   devlink trap group set - set attributes of a packet trap group
       DEV - specifies the devlink device the packet trap group belongs to.

       group GROUP - specifies the packet trap group.

       action { trap | drop | mirror }
              packet trap action. The action is set for all the packet traps member in the trap
              group. The actions of non-drop traps cannot be changed and are thus skipped.

       policer POLICER
              packet trap policer. The policer to bind to the packet trap group. A value of "0"
              will unbind the currently bound policer.

       nopolicer
              Unbind packet trap policer from the packet trap group.

   devlink trap policer set - set attributes of packet trap policer
       DEV - specifies the devlink device the packet trap policer belongs to.

       policer POLICER - specifies the packet trap policer.

       rate RATE - packet trap policer rate in packets per second.

       burst BURST - packet trap policer burst size in packets.
