I posted a new copy of the link ID management API document to: http://www.opensolaris.org/os/project/clearview/uv/link_id_management.pdf
Changes include integrated comments from the SMF folks (change the stop method for system/linkmgmtd and add system/linkmgmtd to the seed repository) and some minor typo corrections. If I missed integrating or responding to anyone's comments, please let me know and I'll take care of it. thanks, Dan
