Daniel Wagner 0fd103ccfe scsi: lpfc: Honor module parameter lpfc_use_adisc 
The initial lpfc_desc_set_adisc implementation in commit
dea3101e0a ("lpfc: add Emulex FC driver version 8.0.28") enabled ADISC if

	cfg_use_adisc && RSCN_MODE && FCP_2_DEVICE

In commit 92d7f7b0cd ("[SCSI] lpfc: NPIV: add NPIV support on top of
SLI-3") this changed to

	(cfg_use_adisc && RSC_MODE) || FCP_2_DEVICE

and later in commit ffc954936b ("[SCSI] lpfc 8.3.13: FC Discovery Fixes
and enhancements.") to

	(cfg_use_adisc && RSC_MODE) || (FCP_2_DEVICE && FCP_TARGET)

A customer reports that after a devloss, an ADISC failure is logged. It
turns out the ADISC flag is set even the user explicitly set lpfc_use_adisc
= 0.

[Sat Dec 22 22:55:58 2018] lpfc 0000:82:00.0: 2:(0):0203 Devloss timeout on WWPN 50:01:43:80:12:8e:40:20 NPort x05df00 Data: x82000000 x8 xa
[Sat Dec 22 23:08:20 2018] lpfc 0000:82:00.0: 2:(0):2755 ADISC failure DID:05DF00 Status:x9/x70000

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
