The driver's management of the fabric controller (aka pseudo-scsi initiator) node in SLI3 mode is causing this crash. The crash occurs because of a node reference imbalance that frees the fabric controller node while devloss is outstanding from the SCSI transport. This is triggered by an odd behavior where the switch reacts to a rejected RDP request with a PLOGI and nothing else, not even a LOGO. The driver ACKS the PLOGI and after successfully registering the RPI, incorrectly registers the fabric controller node because it has the NLP_FC4_FCP flag still set from the fabric controller PRLI. If a LIP is issued, the driver attempts to cleanup on Link Up and ends up executing too many puts. Fix by detecting the fabric node type and clearing out the nodes internal flags that triggered a SCSI transport registration and subsequence dev_loss event. The driver cannot count on any persistence from fabric controller nodes.

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.
