[openib-general] Routing patches

[Yevgeny Kliteynik]

Hi Hal.

Just wanted to put some order in the routing-related patches.

There are four patches that are waiting to be reviewed and applied:

1. Added an option for providing dump function per routing engine
2. [v2] Adding max_lid_ho field to osm_switch_t
3. [v2] Improving FatTree routing engine
4. Added FatTree routing to the osm manual

Thanks.
