I checked the replies while the connection was OK. But clearly the replies can't get in if my network cable is unplugged.
pppoectl shows it stays forever in 'network' state, and there are no LCP timeout messages in console, which should be 
there in normal operation. 

Might it be the peer sending the echo requests? The pppoe RFC recommended that the _server_ should send requests. Maybe 
I'll try if the echoes are sent while the connection is not working.

Weird thing here is, I've configured NetBSD + pppoe multiple times on different machines, and this is the only 
time I'm having problems. Perhaps something has been changed? My kernel WAS 1.6.1_RC2, now it's 1.6.1_STABLE. I haven't 
yet tested if it works with the current kernel.
