satcat5::eth::ProtoEcho Class Reference

Detailed Description

Thin wrapper for echo of ethernet frames through eth::Dispatch.

Note: Always use different request/reply EtherTypes to avoid the potential for infinite reply loops.

The Echo protocol can be attached to any Dispatch object. It copies each received frame back to the original sender. Variants are provided for raw-Ethernet and UDP networking. Generic version requires a wrapper to be used.
