Use the page_pool api for allocations and DMA handling instead of __dev_alloc_page()/dma_map_page() and free_page()/dma_unmap_page(). Pages are unmapped using page_pool_release_page before packets go into the network stack. The page_pool API offers buffer recycling capabilities for XDP but allocates one page per packet, unless the driver splits and manages the allocated page. This is a preliminary patch to add XDP support to mvneta driver Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> 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.
