During a device failover, there may be latency between the loss of the current backing device and a notification from firmware that a failover has occurred. This latency can result in a large amount of error printouts as firmware returns outgoing traffic with a generic error code. These are not necessarily errors in this case as the firmware is busy swapping in a new backing adapter and is not ready to send packets yet. This patch reclassifies those error codes as warnings with an explanation that a failover may be pending. All other return codes will be considered errors.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
