3.11 would suggest you are sticking to Bobs development. There is also 
the "fork" by Mark. Not sure which, if either, is better...

You could crank up the hello timer on the circuit, but I'm not sure 
you'll be much happier with that.
Sounds like you might have some issues with how it performs on the 
ethernet. Hard to tell much without more investigation...
