[openib-general] [PATCHv2] osm: adding max_lid_ho field to osm_switch_t

[Yevgeny Kliteynik]

Hi Hal

[V2 of the patch - removed setter and unnecessary initialization]

Adding max_lid_ho field to osm_switch_t to allow routing
engines that don't use lid matrices to explicitly set the
max lid (in host order) that is reachable from the switch.
