What about the "tail end" of the work, when the limit is reached?
Remember that delaying the completion of TX's too long increases latency.
It seems to me that this patch needs a timer or somesuch, to guarantee
that TX completions are not delayed too long in the worst case.
Yes, you are right.
There is a timer interrupt that fires in throughput mode every 10ms (in
cpu mode it fires at approx every 130us). I can use that to clean out
any uncompleted TXs. Let me know if 10ms is not too late for worst case
tx completion.
