Hi Hal,
This patch optimizes fabric ranking.
All the leaf switches are marked with rank and added to the BFS list,
and only then ranking of rest of the fabric begins.
I actually thought that this is the way I've originally
implemented it, as I mentioned in the patch that was dealing
with 8 and 16 bit integers :)
Similar optimization may be applicable to up/dn routing - the roots
should be marked with rank 0 and only then ranking of rest of the
switches should begin, but frankly, it practically doesn't reduce
the routing time, because ranking is only a small fraction of the
routing runtime (I checked it on a 4K+ subnet).
It's still worth doing IMO. Can you look into this for up/down ?
Sure.

In case of fat-tree I'm going to need it anyway when I enhance
the routing to consider only subset of HCAs in the routing balancing
(compute nodes vs. management nodes).
Please apply to master.

Thanks. Applied (to master only).
