Add support for flexible payloads passed via ethtool user-def field. This support is somewhat limited due to hardware design. The input set can only be programmed once per filter type, and the flexible offset is part of this filter input set. This means that the user cannot program both a regular and a flexible filter at the same time for a given flow type. Additionally, the user may not program two flexible filters of the same flow type with different offsets, although they are allowed to configure different values at that offset location. We support a single flexible word (2byte) value per protocol type, and we handle the FLX_PIT register using a list of flexible entries so that each flow type may be configured separately. Due to hardware implementation, the flexible data is offset from the start of the packet payload, and thus may not be in part of the header data. For this reason, the offset provided by the user defined data is interpreted as a byte offset from the start of the matching payload. Previous implementations have tried to represent the offset as from the start of the frame, but this is not feasible because header sizes may change due to options.

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.
