This patch adds XDP (eXpress Data Path) support to TI AM65 CPSW Ethernet driver. The following features are implemented: - NETDEV_XDP_ACT_BASIC (XDP_PASS, XDP_TX, XDP_DROP, XDP_ABORTED) - NETDEV_XDP_ACT_REDIRECT (XDP_REDIRECT) - NETDEV_XDP_ACT_NDO_XMIT (ndo_xdp_xmit callback) The page pool memory model is used to get better performance. Below are benchmark results obtained for the receiver with iperf3 default parameters: - Without page pool: 495 Mbits/sec - With page pool: 605 Mbits/sec (actually 610 Mbits/sec, with a 5 Mbits/sec loss due to extra processing in the hot path to handle XDP).

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 reStructuredText 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.
