From: Daniel Klein <danielk@xxxxxxxxxxxx> Bug description: When PerfMgr starts discovery, it resets the discovery_count of ports and node, but it doesn't reset the physp_discoved buffers. As a result, the drop manager frees osm_port_t and osm_physp_t objects of nodes without removing the nodes themselves. On the next discovery process, when OpenSM receives responses for NodeInfo from a switch, it treats it as a NodeInfo from an existing node and assumes that osm_physp_t objects of the switch exists and tries to access them. This change adds code that clears the physp_discoverd buffers of all nodes at the beginning of the discovery process in PerfMgr.
