changing Length of the Reflected Packet and Number of the Reflected Packets
to two-byte length.

GIM>> That is interesting idea, thank you! I agree that Reflected Test
Packet Control TLV is logical construct to convey information necessary to
conduct HBH on-path telemetry. I think that it can be defined in
draft-fioccola-ippm-on-path-active-measurements and change it to Standard
track. WDYT?
