The issue here is distinguishing failure cases. I'm leery of defining  
and interface where FAIL means "not acked," because it does not let  
the higher layer distinguish "I am broken" from "sure, retry." E.g.,  
CTP would respond very different, with respect to retries and its link  
estimation, between the lower stack failing and a packet not being  
acked.
