I think I haven't replied to you on the config recommendation about
how global vs per-object config should behave. I implemented the
suggested scheme for rx-buf-len to make sure its not a crazy ask:
https://lore.kernel.org/all/20250421222827.283737-1-kuba@kernel.org/
and I do like it more.
Joe, Stanislav and Mina all read that series and are CCed here.
What do y'all think? Should we make the threaded config work like
the rx-buf-len, if user sets it on a NAPI it takes precedence
over global config? Or stick to the simplistic thing of last
write wins?
