2016-08-02	iw_cm: free cm_id resources on the last deref	Steve Wise	1	-1/+1
	Remove the complicated logic to free the iw_cm_id inside iw_cm event handlers vs when an application thread destroys the cm_id. Also remove the block in iw_destroy_cm_id() to block the application until all references are removed. This block can cause a deadlock when disconnecting or destroying cm_ids inside an rdma_cm event handler. Simply allowing the last deref of the iw_cm_id to free the memory is cleaner and avoids this potential deadlock. Also a flag is added, IW_CM_DROP_EVENTS, that is set when the cm_id is marked for destruction. If any events are pending on this iw_cm_id, then as they are processed they will be dropped vs posted upstream if IW_CM_DROP_EVENTS is set.

2006-09-22	RDMA: iWARP Connection Manager.	Tom Tucker	1	-0/+62
	Add an iWARP Connection Manager (CM), which abstracts connection management for iWARP devices (RNICs). It is a logical instance of the xx_cm where xx is the transport type (ib or iw). The symbols exported are used by the transport independent rdma_cm module, and are available also for transport dependent ULPs.
