Adds basic XDP support i.e attaching a BPF program to an interface. Also takes care of allocating separate Tx queues for XDP path and for network stack packet transmission. This patch doesn't support handling of any of the XDP actions, all are treated as XDP_PASS i.e packets will be handed over to the network stack. Changes also involve allocating one receive buffer per page in XDP mode and multiple in normal mode i.e when no BPF program is attached.

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.
