commit0956ba63bdupstream. A commit introduced formal regstration of all Fabric nodes to the SCSI transport as well as REG/UNREG RPI mailbox requests. The commit introduced the NLP_RELEASE_RPI flag for rports set in the lpfc_cmpl_els_logo_acc() routine to help clean up the RPIs. This new code caused the driver to release the RPI value used for the remote port and marked the RPI invalid. When the driver later attempted to re-login, it would use the invalid RPI and the adapter rejected the PLOGI request. As no login occurred, the devloss timer on the rport expired and connectivity was lost. This patch corrects the code by removing the snippet that requests the rpi to be unregistered. This change only occurs on a node that is already marked to be rediscovered. This puts the code back to its original behavior, preserving the already-assigned rpi value (registered or not) which can be used on the re-login attempts.

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.
