While the default did already correctly print "Initiator" let's make it
explicit and convert zfcp to the feature.
$ cat /sys/class/scsi_host/host0/supported_mode
Initiator
$ cat /sys/class/scsi_host/host0/active_mode
Initiator
The default worked, because not setting the field has it initialized to zero
== MODE_UNKNOWN. scsi_host_alloc() sets shost->active_mode = MODE_INITIATOR
in this case. The sysfs accessor function show_shost_supported_mode()
assumes MODE_INITIATOR in this case. This default behavior was introduced
with v2.6.24 commit 7a39ac3f25be ("[SCSI] make supported_mode default to
initiator."). The feature flag was introduced with v2.6.24 commit
5dc2b89e1242 ("[SCSI] add supported_mode and active_mode attributes to the
host"). So there was no release where zfcp would have shown "unknown".

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
