Denis Kirjanov says: ==================== xen networking: add XDP support to xen-netfront The first patch adds a new extra type to enable proper synchronization between an RX request/response pair. The second patch implements BFP interface for xen-netfront. The third patch enables extra space for XDP processing. v14: - fixed compilation warnings v13: - fixed compilation due to previous rename v12: - xen-netback: rename netfront_xdp_headroom to xdp_headroom v11: - add the new headroom constant to netif.h - xenbus_scanf check - lock a bulk of puckets in xennet_xdp_xmit() v10: - add a new xen_netif_extra_info type to enable proper synchronization between an RX request/response pair. - order local variable declarations v9: - assign an xdp program before switching to Reconfiguring - minor cleanups - address checkpatch issues v8: - add PAGE_POOL config dependency - keep the state of XDP processing in netfront_xdp_enabled - fixed allocator type in xdp_rxq_info_reg_mem_model() - minor cleanups in xen-netback v7: - use page_pool_dev_alloc_pages() on page allocation - remove the leftover break statement from netback_changed v6: - added the missing SOB line - fixed subject v5: - split netfront/netback changes - added a sync point between backend/frontend on switching to XDP - added pagepool API v4: - added verbose patch descriprion - don't expose the XDP headroom offset to the domU guest - add a modparam to netback to toggle XDP offset - don't process jumbo frames for now v3: - added XDP_TX support (tested with xdping echoserver) - added XDP_REDIRECT support (tested with modified xdp_redirect_kern) - moved xdp negotiation to xen-netback v2: - avoid data copying while passing to XDP - tell xen-netback that we need the headroom space ==================== Signed-off-by: David S.

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.
