This program is similar to ping, but tests connectivity at the link layer (layer 2) instead of the network layer (layer 3). This works like the HP-UX linkloop utility. It was tested between Linux and HP-UX (both ways). There is also a "server-side" utility for Linux (linkloop_reply). There are plans to move the "reply" support into the kernel.
