Attached is the ELS/CT pass-thru patch for the FC Transport. The patch
creates a generic framework that lays on top of bsg and the SGIO v4 ioctl
in order to pass transaction requests to LLDD's.
The interface supports the following operations:
On an fc_host basis:
Request login to the specified N_Port_ID, creating an fc_rport.
Request logout of the specified N_Port_ID, deleting an fc_rport
Send ELS request to specified N_Port_ID w/o requiring a login, and
wait for ELS response.
Send CT request to specified N_Port_ID and wait for CT response.
Login is required, but LLDD is allowed to manage login and decide
whether it stays in place after the request is satisfied.
Vendor-Unique request. Allows a LLDD-specific request to be passed
to the LLDD, and the passing of a response back to the application.
On an fc_rport basis:
Send ELS request to nport and wait for ELS response.
Send CT request to nport and wait for CT response.
The patch also exports several headers from include/scsi such that
they can be available to user-space applications:
include/scsi/scsi.h
include/scsi/scsi_netlink.h
include/scsi/scsi_netlink_fc.h
include/scsi/scsi_bsg_fc.h
For further information, refer to the last RFC:

Note: Documentation is still spotty and will be added later.
