James Smart ea92e173dc scsi: lpfc: Fix lost NVMe paths during LIF bounce stress test
During a target link bounce test, the driver sees a mismatch between the
NPortId and the WWPN on the node structures (ndlps) involved.  When this
occurs, the driver "swaps" the ndlp and new_ndlp node parameters to restore
WWPN/DID uniqueness in the fc_nodes list per vport.  However, the driver
neglected to swap the nlp_fc4_type in the ndlp passed to
lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI
and ultimately the NVMe paths.

Correct confirm_nport to preserve the fc4 types from the new-ndlp when the
data is moved over ot the ndlp structure.

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.
