Tariq Toukan says: ==================== net/mlx5e: Extend XDP multi-buffer capabilities This series extends the XDP multi-buffer support in the mlx5e driver. Patchset breakdown: - Infrastructural changes and preparations. - Add XDP multi-buffer support for XDP redirect-in. - Use TX MPWQE (multi-packet WQE) HW feature for non-linear single-segmented XDP frames. - Add XDP multi-buffer support for striding RQ. In Striding RQ, we overcome the lack of headroom and tailroom between the RQ strides by allocating a side page per packet and using it for the xdp_buff descriptor. We structure the xdp_buff so that it contains nothing in the linear part, and the whole packet resides in the fragments. Performance highlight: Packet rate test, 64 bytes, 32 channels, MTU 9000 bytes. CPU: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz. NIC: ConnectX-6 Dx, at 100 Gbps. +----------+-------------+-------------+---------+ | Test | Legacy RQ | Striding RQ | Speedup | +----------+-------------+-------------+---------+ | XDP_DROP | 101,615,544 | 117,191,020 | +15% | +----------+-------------+-------------+---------+ | XDP_TX | 95,608,169 | 117,043,422 | +22% | +----------+-------------+-------------+---------+ Series generated against net commit: e61caf04b9f8 Merge branch 'page_pool-allow-caching-from-safely-localized-napi' I'm submitting this directly as Saeed is traveling. ==================== 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.
