it looks like you and Krishna use the same requeueing methods - get one
from qdisk, queue it into blist, get next from qdisk, queue it,
eventually start transmit, where you dequeue it one-by-one and send (or
prepare and commit). This is not the 100% optimal approach, but if you
proved it does not hurt usual network processing, it is ok.
Number of comments dusted to very small - that's a sign, but I'm a bit
lost - did you and Krishna create the competing approaches, or they can
co-exist together, in the former case I doubt you can push, until all
problematic places are resolved, in the latter case, this is probably
ready.
