Introduce page_pool support in veth driver in order to recycle pages in veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb through the page allocator. The patch has been tested sending tcp traffic to a veth pair where the remote peer is running a simple xdp program just returning xdp_pass: veth upstream codebase: MTU 1500B: ~ 8Gbps MTU 8000B: ~ 13.9Gbps veth upstream codebase + pp support: MTU 1500B: ~ 9.2Gbps MTU 8000B: ~ 16.2Gbps Tested-by: Maryam Tahhan <mtahhan@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
