Thanks for the comments so far.

Does the ethernet keepalive mechanism have any value when the
interface is operating in full duplex mode?  Will the remote-end
reply or echo the frame?  

In full duplex mode, the interface is not actively sensing the
transmission, right?   So how does the interface know that
transmission was really successful.

Thanks
