This patch set is a request to incorporate the new Broadcom
(Emulex) FC target driver, efct, into the kernel source tree.
The driver source has been Announced a couple of times, the last
version on 12/18/2018. The driver has been hosted on gitlab for
review has had contributions from the community.
gitlab (git@xxxxxxxxxx:jsmart/efct-Emulex_FC_Target.git)
The driver integrates into the source tree at the (new) drivers/scsi/elx
subdirectory.
The driver consists of the following components:
- A libefc_sli subdirectory: This subdirectory contains a library that
encapsulates common definitions and routines for an Emulex SLI-4
adapter.
- A libefc subdirectory: This subdirectory contains a library of
common routines. Of major import is a number of routines that
implement a FC Discovery engine for target mode.
- An efct subdirectory: This subdirectory contains the efct target
mode device driver. The driver utilizes the above librarys and
plugs into the SCSI LIO interfaces. The driver is SCSI only at
this time.
The patches populate the libraries and device driver and can only
be compiled as a complete set.
This driver is completely independent from the lpfc device driver
and there is no overlap on PCI ID's.
The patches have been cut against the 5.6/scsi-queue branch.
Thank you to those that have contributed to the driver in the past.
Review comments welcome!

V2 modifications:
Contains the following modifications based on prior review comments:
Indentation/Alignment/Spacing changes
Comments: format cleanup; removed obvious or unnecessary comments;
Added comments for clarity.
Headers use #ifndef comparing for prior inclusion
Cleanup structure names (remove _s suffix)
Encapsulate use of macro arguments
Refactor to remove static function declarations for static local routines
Removed unused variables
Fix SLI4_INTF_VALID_MASK for 32bits
Ensure no BIT() use
Use __ffs() in page count macro
Reorg to move field defines out of structure definition
Commonize command building routines to reduce duplication
LIO interface:
Removed scsi initiator includes
Cleaned up interface defines
Removed lio WWN version attribute.
Expanded macros within logging macros
Cleaned up lio state setting macro
Remove __force use
Modularized session debugfs code so can be easily replaced.
Cleaned up abort task handling. Return after initiating.
Modularized where possible to reduce duplication
Convert from kthread to workqueue use
Remove unused macros
Add missing TARGET_CORE build attribute
Fix kbuild test robot warnings
Comments not addressed:
Use of __packed: not believed necessary
Session debugfs code remains. There is not yet a common lio
mechanism to replace with.
