Interfaces bound to DPDK (e.g. by VPP) are detached from the kernel
driver, so the ethtool plugin cannot report their ENA extended
statistics (pps_allowance_exceeded, bw_*_allowance_exceeded,
conntrack_allowance_exceeded, rx_missed_errors, ...). Enable the
upstream telegraf dpdk input, which reads the same stats from the DPDK
v2 telemetry socket, and add a "dpdk" section under
metrics_collected so it can be configured from the agent JSON config:
"dpdk": {
"socket_path": "/var/run/dpdk/rte/dpdk_telemetry.v2",
"device_types": ["ethdev"],
"metrics_include": ["pps_allowance_exceeded", ...]
}
