[ Upstream commit a8168b6cee6e9334dfebb4b9108e8d73794f6088 ] On some dual port NICs, the 2 ports have to be configured with compatible link speeds. Under some conditions, a port's configured speed may no longer be supported. The firmware will send a message to the driver when this happens. Improve this logic that prints out the warning by only printing it if we can determine the link speed that is no longer supported. If the speed is unknown or it is in autoneg mode, skip the warning message.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
