[ Upstream commit 9d92cfeaf5215158d26d2991be7f7ff865cb98f3 ]
The counters on M3UPI Link 0 and Link 3 don't count properly, and writing
0 to these counters may causes system crash on some machines.
The PCI BDF addresses of the M3UPI in the current code are incorrect.
The correct addresses should be:
D18:F1 0x204D
D18:F2 0x204E
D18:F5 0x204D

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.
