By this commit, using `bpftool net attach`, user can attach XDP prog on interface. New type of enum 'net_attach_type' has been made, as stat ted at cover-letter, the meaning of 'attach' is, prog will be attached on interface. With 'overwrite' option at argument, attached XDP program could be replaced. Added new helper 'net_parse_dev' to parse the network device at argument. BPF prog will be attached through libbpf 'bpf_set_link_xdp_fd'. Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel T.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
