The thing is that for data-path changes on high performance network
drivers, we @ least need to know that the perf is as good as it was
before the change. So you could run your iser perf IOPS test
before/after the change and post 1-2 lines with results as part of the
change-log.
I tested iser perf and it seems to sustain. I didn't see any major
difference but I really don't think block storage iops/latency is not
the correct way to evaluate this change.
maybe one nice option would be to take a look on how things are
organized in libmlx5 around that corner
