commite52d484d98upstream. System gets checkstop if RxFIFO overruns with more requests than the maximum possible number of CRBs in FIFO at the same time. The max number of requests per window is controlled by window credits. So find max CRBs from FIFO size and set it to receive window credits.

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.
