James Smart 358b37c6c6 scsi: lpfc: Fix unexpected error messages during RSCN handling
[ Upstream commit 2332e6e475b016e2026763f51333f84e2e6c57a3 ]

During heavy RCN activity and log_verbose = 0 we see these messages:

  2754 PRLI failure DID:521245 Status:x9/xb2c00, data: x0
  0231 RSCN timeout Data: x0 x3
  0230 Unexpected timeout, hba link state x5

This is due to delayed RSCN activity.

Correct by avoiding the timeout thus the messages by restarting the
discovery timeout whenever an rscn is received.

Filter PRLI responses such that severity depends on whether expected for
the configuration or not. For example, PRLI errors on a fabric will be
informational (they are expected), but Point-to-Point errors are not
necessarily expected so they are raised to an error level.

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.
