The driver is getting hit with 100s of RSCNs during remote port address changes. Each of those RSCN's ends up generating UNREG_RPI and REG_PRI mailbox commands. The discovery engine within the driver doesn't wait for the mailbox command completions. Instead it sets state flags and moves forward. At some point, there's a massive backlog of mailbox commands which take time for the adapter to process. Additionally, it appears there were duplicate events from the switch so the driver generated duplicate mailbox commands for the same remote port. During this window, failures on PLOGI and PRLI ELS's are see as the adapter is rejecting them as they are for remote ports that still have pending mailbox commands. Streamline the discovery engine so that PLOGI log checks for outstanding UNREG_RPIs and defer the processing until the commands complete. This better synchronizes the ELS transmission vs the RPI registrations. Filter out multiple UNREG_RPIs being queued up for the same remote port. Beef up log messages in this area.

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.
