From: Jiri Pirko <j...@mellanox.com> Nogah says:
For a packet to be sent from the HW to the cpu, it needs to be trapped. For a trap to be activate it should be assigned to a trap group. Those trap groups can have policers, to limit the packet rate (the max number of packets that can be sent to the cpu in a time slot, the rest will be discarded) or the data rate (the same, but the count is not by the number of packets but by their total length in bytes). This patchset rearrange the trap setting API, re-write the traps and the trap groups list in spectrum and assign them policers.
