ip stats [command] [options]

ip stats manages and displays network interface statistics. It provides access to both software-maintained counters and hardware offload statistics where supported.
Statistics groups include link-layer counters, hardware offload metrics, and address-family specific statistics like MPLS. Hardware statistics collection may need to be explicitly enabled.

Enable/disable L3 hardware statistics

Hardware offload statistics require driver and hardware support. Some statistics may not be available on all interfaces. Enabling statistics collection may have a performance impact.

ip stats was added to iproute2 to provide unified access to various network statistics including hardware offload metrics that became available in newer kernel versions.
