After fine-tuning qdisc and other changes, I modified IPoIB to use this API,
and now get good gains. Summary for TCP & No Delay: 1 process improves for
all cases from 1.4% to 49.5%; 4 process has almost identical improvements
from -1.7% to 59.1%; 16 process case also improves in the range of -1.2% to
33.4%; while 64 process doesn't have much improvement (-3.3% to 12.4%). UDP
was tested with 1 process netperf with small increase in BW but big
improvement in Service Demand. Netperf latency tests show small drop in
transaction rate (results in separate attachment).

What about round-robin tcp time and latency test? In theory such batching
mode should not change that timings, but practice can show new aspects.
I will review code later this week (likely tomorrow) and if there will
be some issues return back.
