Verify that NPU (integrated-circuit) pipeline drop counters are reported correctly via telemetry and correctly increment under conditions that induce the respective drops.

• //topologies/kne/dut_ate_2links.testbed

• Configure interfaces between ATE and DUT.
• Configure IPv4/IPv6 addressing.
• Enable telemetry for the /components/component/integrated-circuit/pipeline-counters/drop/vendor path.

{}

• Verify via telemetry that /components/component[name=<node>:<npu>]/integrated-circuit/pipeline-counters/drop/vendor/CiscoXR/spitfire/packet-processing/state/L3_ROUTE_LOOKUP_FAILED exists and returns a non-negative value.

• Configure a static route on the DUT pointing to Null0 (discard interface).
• From ATE Port-1, send traffic destined to the prefix configured in the Null0 route.
• Verify via telemetry that /components/component[name=<node>:<npu>]/integrated-circuit/pipeline-counters/drop/vendor/CiscoXR/spitfire/packet-processing/state/L3_NULL_ADJ increments.

• Verify via telemetry that /components/component[name=<node>:<npu>]/integrated-circuit/pipeline-counters/drop/vendor/CiscoXR/spitfire/packet-processing/state/MPLS_TE_MIDPOINT_LDP_LABELS_MISS exists and returns a non-negative value.
