firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.
