James Smart 92ea83a878 scsi: lpfc: rport port swap discovery issue.
Two initiator ports were cable swapped and after swap both went down.  The
driver internally swaps the nlp nodes based on matching node wwn's but not
the same nport id as before. After detecting a change in the nodes RPI, the
driver sends an UNREG_RPI command and clears the NLP_RPI_REGISTERED flag,
then swaps the node information with the other node. But the other node's
NLP_RPI_REGISTERED flag is also cleared, but it is done so without an
UNREG_RPI being sent, which causes the later REG_RPI for that other node to
fail as the hardware believes its still registered.

Additionally, if the node swap occurred while the two nodes had PLOGI's in
flight, the fc4_types weren't properly getting swapped such that when the
PLOGIs commpleted and PRLI's were then sent, the PRLI's acted on bad
protocol types so the PRLI was for the wrong protocol. NVME devices saw
SCSI FCP PRLIs and vice versa.

Clean up the node swap so that the NLP_RPI_REGISTERED flag is handled
properly.

Fix the handling of the fc4_types when the nodes are swapped as well

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.
