Perhaps spending some time reading the list would help you understand
what normal development upstream looks like. Posting the N + 1 version
of a patch set and then replying to comments on version N is confusing
because it's impossible to decide where the conversation is taking
place. Should I reply to you on version N or reply to N + 1 even tho
there I can't quote your reply. And will the maintainer who's applying
the patches understand that N + 1 got rejected if the discussion is
happening under the thread of version N?

Perhaps one has to read the list to appreciate the challenges involved.

Sounds good, but please make sure you describe the interaction between
the params and the algorithm. We don't have a SW implementation like we
have for qdiscs here, and we don't want each vendor to be coming up
with their own interpretation of the arguments. So we need solid docs,
and some pseudo code to describe the behavior, perhaps?

Let me ask some extra questions on the doc.
