Presumably octeon doesn't do speculative writes, only *buffered* writes.
So writes move down, not up.
But it looks like Cavium is one of those clown companies that have a
"contact us" button for technical documentation rather than actually
making it available.

technical details? Seriously, that just stinks of "we have so many
bugs that we cannot make the documentation available".
