Could you please share your thoughts on why it's hard to judge them and
what's missing from the series, such as in the comments, changelog, or
the cover letter?
My main concern (as shared on earlier revisions) is the type hierarchy
exposed to the drivers. Converting things back and forth or blindly
downcasting to netmem and upcasting back to the CPU-readable type is
no good.
I understand your concern.  I removed a lot of converting things but
left essencial things, that is inevitable to remove accessing the pp
fields through struct page.  Is it still not okay with v10 [1]?

There are some points under disscussion with Mina but I'm curious about
how you think about the direction changed.
