I don't have any guests with PAGE_SIZE > 64k but the
code seems to be clearly broken in that case
as PAGE_SIZE / MERGEABLE_BUFFER_ALIGN will need
more than 8 bit and so the code in mergeable_ctx_to_buf_address
does not give us the actual true size.

Applied, thanks Michael.

I am really trying to be patient, but we are about to run out of
time for fixing the adjust header XDP stuff.

That should have been resolved in a week or two, but now we're
basically a month or so later.

Please come to some kind of agreement about how to implement this
because we can't let v4.10 go out without this being resolved.

Thank you.

I didn't realise. Why can't we? I thought that adjust_header is an
optional feature that userspace can test for, so no rush.
