This library negotiates a PPPoE channel. It handles the discovery stage and leaves the session stage to the kernel. A further PPP library is needed to actually set up a PPP unit (negotatie LCP, IPCP and do authentication), so in isolation this is not yet very useful.
The test program has two modes:
will create a veth tunnel in a new network namespace, start pppoe-server on one end and this client library on the other. The pppd server will time out as no LCP is performed, and the client will then shut down gracefully.
# ./test-pppoe eth0
will run the client on eth0 (or any other netdev), and requires a PPPoE server to be reachable on the local link.
