This patch tries to export some generic xdp helpers to drivers. This can let driver to do XDP for a specific skb. This is useful for the case when the packet is hard to be processed at page level directly (e.g jumbo/GSO frame). With this patch, there's no need for driver to forbid the XDP set when configuration is not suitable. Instead, it can defer the XDP for packets that is hard to be processed directly after skb is created. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S.

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.
