When setting a policer to a trap group, a value of "0" will unbind the
currently bound policer from the group.
The behavior is intentional and tested in kernel selftests, so document
it.

Add ability to associate a policer with a trap group. The policer can be
unbound by using the 'nopolicer' keyword. In which case, the value
encoded in the 'DEVLINK_ATTR_TRAP_POLICER_ID' attribute will be '0'.
This is consistent with ip-link 'nomaster' keyword and the 'IFLA_MASTER'
attribute.
Example:
# devlink trap group set netdevsim/netdevsim10 group l3_drops policer 2
# devlink -jp trap group show netdevsim/netdevsim10 group l3_drops
{
"trap_group": {
"netdevsim/netdevsim10": [ {
"name": "l3_drops",
"generic": true,
"policer": 2
} ]
}
}
# devlink trap group set netdevsim/netdevsim10 group l3_drops nopolicer
# devlink -jp trap group show netdevsim/netdevsim10 group l3_drops
{
"trap_group": {
"netdevsim/netdevsim10": [ {
"name": "l3_drops",
"generic": true
} ]
}
}

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
{
"trap_policer": {
"netdevsim/netdevsim10": [ {
"policer": 1,
"rate": 1000,
"burst": 32,
"stats": {
"rx": {
"dropped": 53
}
}
} ]
}
}
