David S. Miller cc8f1a3979 Merge branch 'tap-XDP-support'
Jason Wang says:

====================
XDP support for tap

This series tries to implement XDP support for tap. Two path were
implemented:

- fast path: small & non-gso packet, For performance reason we do it
  at page level and use build_skb() to create skb if necessary.
- slow path: big or gso packet, we don't want to lose the capability
  compared to generic XDP, so we export some generic xdp helpers and
  do it after skb was created.

xdp1 shows about 41% improvement, xdp_redirect shows about 60%
improvement.

Changes from V1:
- fix the race between xdp set and free
- don't hold extra refcount
- add XDP_REDIRECT support

Please review.

README

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.
