aq_xdp() is a xdp setup callback function for Atlantic driver. When XDP is attached or detached, the device will be restarted because it uses different headroom, tailroom, and page order value. If XDP enabled, it switches default page order value from 0 to 2. Because the default maximum frame size is still 2K and it needs additional area for headroom and tailroom. The total size(headroom + frame size + tailroom) is 2624. So, 1472Bytes will be always wasted for every frame. But when order-2 is used, these pages can be used 6 times with flip strategy. It means only about 106Bytes per frame will be wasted. Also, It supports xdp fragment feature. MTU can be 16K if xdp prog supports xdp fragment. If not, MTU can not exceed 2K - ETH_HLEN - ETH_FCS. And a static key is added and It will be used to call the xdp_clean handler in ->poll(). data plane implementation will be contained the followed patch.

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.
