Mainline Linux tree for various devices, only for fun :)

Following steps are taken in the driver to offload an XDP program: XDP_SETUP_PROG: * prepare: - allocate program state; - run verifier (bpf_analyzer()); - run translation; * load: - stop old program if needed; - load program; - enable BPF if not enabled; * clean up: - free program image. With new infrastructure the flow will look like this: BPF_OFFLOAD_VERIFIER_PREP: - allocate program state; BPF_OFFLOAD_TRANSLATE: - run translation; XDP_SETUP_PROG: - stop old program if needed; - load program; - enable BPF if not enabled; BPF_OFFLOAD_DESTROY: - free program image. Take advantage of the new infrastructure. Allocation of driver metadata has to be moved from jit.c to offload.c since it's now done at a different stage. Since there is no separate driver private data for verification step, move temporary nfp_meta pointer into nfp_prog. We will now use user space context offsets.

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.
