Hey,
As Saeed said, we discussed different APIs for this, debugfs seemed like
the best fit as we don't want users to change the queues parameters for
production purposes. Debugfs makes it clear that these params aren't for
your ordinary use, and allows us to be more flexible over time if needed
(we don't necessarily have to keep these files there forever, if our
hardware implementation changes for example).
Devlink param would work, but the message conveyed is a bit different
:). It makes it seem like this is a knob we want people to play with.
(And we have to support it forever).
