Follow-up Comment #10, task #14128 (project lwip):
Mailing list post, including patch:
http://marc.info/?l=linux-netdev&m=138324287502447&w=2
Unfortunately, there seems to be no discussion of the burstiness tradeoff per
RTT by employing ABC with no limit.
I don't have a concrete understanding of how often stretch ACKs (where the
span is greater than 2 SMSS) occurrs, but I've observed some instances to
suggest it does exist in the wild (though large packet loss could also explain
the behavior)
Given that delayed ACKs are very common, including LwIP, I would say we should
be supporting stretch ACKs up to 2 SMMS. In terms of going beyond that, I'm
not sure if I have enough data to show it's a good tradeoff
