I did not understand...
The only difference from 2.0 is that we clone skbs and, hence, have no device lock, but it did not help to PREVENT drops in any case because affects only retransmissions. If 2.0 really behaves better, it requires explanation.
BTW it is easy to make static clamping ssthresh and snd_cwnd, based on routing tables. Probably, it will really help folks with slow links.
