For information on the interfaces and design, please read the Documentation/scsi/scsi_fc_transport.txt file enclosed within the patch. The RFC was originally posted here: http://marc.info/?l=linux-scsi&m=117226959918393&w=2 Changes from the initial RFC: - Bug fix: needed a transport_class_unregister() for the vport class - Create a symlink to the vport in the shost device if it is not the parent of the vport. - Made symbolic name writable so it can be set after creation - Made the temporary fc_vport_identifiers struct private to the transport. - Deleted the vport_id field from the vport. I couldn't find any good use for it (and symname is a good replacement). - Made the vport_state and vport_last_state "private" attributes. Added the fc_vport_set_state() helper function to manage state transitions - Updated vport_create() to allow a vport to be created in a disabled state. - Added INITIALIZING and FAILED vport states - Added VPCERR_xxx defines for errors to be returned from vport_create() - Created a Documentation/scsi/scsi_fc_transport.txt file that describes the interfaces and expected LLDD behaviors.
