This read-only value reports the number of hops needed to reach the desired destination node for this SMDS circuit entry, analogous to cktLeafHopCnt but specific to the SMDS routing context. This gives a quick complexity/distance metric for the computed SMDS route, useful for comparing against alternate paths or for flagging unexpectedly long routes that might indicate suboptimal routing. An engineer noticing SMDS traffic taking longer than expected would check cktSmdsHopCnt to see if the route is unnecessarily long compared to the network's actual topology.
