	Thats right. But what about the other cases of retransmission 
failures for which we are having a negative return (-ENOMEM, -EAGAIN, 
-EHOSTUNREACH etc). Even for these cases its not a good idea to 
artificially increment tp->retransmits, lest in some extreme case we might 
timeout a connection without a single packet going on the wire.

That's just like the packet getting dropped at the next hop,
and not the case this branch of code intends to deal with.
