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.
Christ, why would anybody do business with a tech company that hides technical details? Seriously, that just stinks of "we have so many bugs that we cannot make the documentation available".
