Note over NETDEV

Note over NETDEV streams kernel tracing or instrumentation data (e.g., scheduler events, interrupts, context switches) to a remote host for analysis. It is one-way communication over UDP.

The netdev driver selected by CONFIG_DRIVERS_NOTENET_INTF must be based on the Netdev Lowerhalf implementation, and CONFIG_NET_NETPOLL must be enabled. Notes are sent as raw note records to CONFIG_DRIVERS_NOTENET_IPADDR / CONFIG_DRIVERS_NOTENET_MAC on UDP port CONFIG_DRIVERS_NOTENET_PORT (broadcast by default).
