Counter for drop packets at the Ingress/interface stage

L2 Linker

Is there any specific counter  to tell if traffic is being dropped during high-dataplane utilization ~100%.

The show counter interface <interface> specifies dropped packets & packets dropped due to flow state checks. but will there be any slighest chance that we are dropping traffic because the chip buffers are under severe load.
