Its possible that a scsi ID of a target can change due to some fabric changes. The WWPN of the scsi target provides a better way to identify the target. Also, add flags for receiving MAD versioning information and advertising client support for targetWWPN with the VIOS. This latter capability flag will be required for future clients capable of requesting multiple hardware queues from the host adapter.
