Add the following ring flag: - IGB_RING_FLAG_TX_DISABLED (when xsk pool is being setup) Add a xdp_buff array for use with XSK receive batch API, and a pointer to xsk_pool in igb_adapter. Add enable/disable functions for TX and RX rings. Add enable/disable functions for XSK pool. Add xsk wakeup function. None of the above functionality will be active until NETDEV_XDP_ACT_XSK_ZEROCOPY is advertised in netdev->xdp_features.

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.
