Currently, every packet that matches a mirroring trigger (e.g., received packets, buffer dropped packets) is mirrored. Spectrum-2 and later ASICs support mirroring with probability, where every 1 in N matched packets is mirrored. Extend the API that creates the binding between the trigger and the SPAN agent with a probability rate parameter, which is an attribute of the trigger. Set it to '1' to maintain existing behavior. Subsequent patches will use it to perform more sophisticated sampling, by mirroring packets to the CPU with probability.
