The management firmware is running on a Big Endian processor, and when running on LE platform HW is configured to swap access to memory shared between management firmware and driver on 32-bit granulariy. As a result, for matters of simplicity most of the APIs between driver and management firmware are based on 32-bit variables. MAC settings are one exception, as driver needs to fill a byte array when indicating to management firmware that primary MAC has changed. Due to the swap, driver must make sure that the mac that was provided in byte-order would be translated into native order, otherwise after the swap the management firmware would read it swapped.

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.
