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

              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.
