Leon,
We don't fence those WR's.
Christoph just re-write it to be more intuitive code. I don't see logic
difference, am I wrong here ?
A little bit, before Christoph's suggestion, we calculated fence for
the paths which need such fence, after we will calculate for all paths.
Every WQE posted to a send queue must include a fence bit. All work
request posted on the send queue calculate the required fence, this
used to happen in finish_wqe call-sites with get_fence(), Christoph
just inlin'ed it.
