2007-07-10IB/cm: Include HCA ACK delay in local ACK timeoutSean Hefty
The IB CM should include the HCA ACK delay when calculating the local ACK timeout value to use for RC QPs. If the HCA ACK delay is large enough relative to the packet life time, then if it is not taken into account, the calculated timeout value ends up being too small, which can result in "retry exceeded" errors.

2006-11-29IB/cm: Fix automatic path migration supportSean Hefty
The ib_cm_establish() function is replaced with a more generic ib_cm_notify(). This routine is used to notify the CM that failover has occurred, so that future CM messages (LAP, DREQ) reach the remote CM. (Currently, we continue to use the original path) This bumps the userspace CM ABI. New alternate path information is captured when a LAP message is sent or received. This allows QP attributes to be initialized for the user when a new path is loaded after failover occurs.

2006-06-17IB/ucm: Get rid of duplicate P_Key parameterSean Hefty
The P_Key is provided into a SIDR REQ in two places, once as a parameter, and again in the path record. Remove the P_Key as a parameter and always use the one given in the path record. This change has no practical effect on ABI functionality. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-06-17IB/cm: Match connection requests based on private dataSean Hefty
Extend matching connection requests to listens in the InfiniBand CM to include private data checks. This allows applications to listen on the same service identifier, with private data directing the request to the appropriate application.

2005-10-17[IB] CM: bind IDs to a specific deviceSean Hefty
Bind communication identifiers to a device to support device removal. Export per HCA CM devices to userspace. Signed-off-by: Sean Hefty <sean.hefty@intel.com>

2005-08-26[PATCH] IB: move include files to include/rdmaRoland Dreier
Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>
