The trap policer set command allows the user to set the parameters of
the packet trap policer, such as rate and burst size. Example:
# devlink trap policer set netdevsim/netdevsim10 policer 1 rate 1000 burst 32
The trap policer show command allows the user to get the current
parameters of an individual policer or a dump of all policers in case
one is not specified. When '-s' is specified the policer's statistics
are shown. Example:
# devlink -jps trap policer show netdevsim/netdevsim10 policer 1
