Devices that support FLAG2_DMA_BURST have different default values for RDTR and RADV. Apply burst mode default settings only when no explicit value was passed at module load. The RDTR default is zero. If the module is loaded for low latency operation with RxIntDelay=0, do not override this value with a burst default of 32. Move the decision to apply burst values earlier, where explicitly initialized module variables can be distinguished from defaults.

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.
