Systems with large MRRS on device (2K, 4K) with high data rates and/or large MTU, atlantic observes DMA packet buffer overflow. On some systems that causes PCIe transaction errors, hardware NMIs or datapath freeze. This patch 1) Limits MRRS from device side to 2K (thats maximum our hardware supports) 2) Limit maximum size of outstanding TX DMA data read requests. This makes hardware buffers running fine.

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.
