Unlike the existing mlxsw traps, ACL traps are "source traps". That means the action is not controlled by HPKT register but directly in ACL TRAP action. When devlink user changes action from drop to trap and vice versa, it would be needed to go over all instances of ACL TRAP action and do change. That does not scale. Instead, resolve this by introducing "dummy" group with "thin" policer. The purpose of this policer is to drop as many packets as possible. The ones that pass through are going to be dropped in devlink code - patch #6 takes care of that. First four patches are preparation for introduction of ACL traps in mlxsw so it possible to easily change from drop to trap for source traps as well - by changing group to "dummy" and back. ==================== Signed-off-by: David S.
