Roger Quadros says: ==================== net: ethernet: ti: am65-cpsw: Add multi queue RX support am65-cpsw can support up to 8 queues at Rx. So far we have been using only one queue (i.e. default flow) for all RX traffic. This series adds multi-queue support. The driver starts with 1 RX queue by default. User can increase the RX queues via ethtool, e.g. 'ethtool -L ethx rx <N>' The series also adds regmap and regfield support to some of the ALE registers. It adds Policer/Classifier registers and fields. Converting the existing ALE control APIs to regfields can be a separate exercise. Some helper functions are added to read/write to the Policer/Classifier registers and a default Classifier setup function is added that routes packets based on their PCP/DSCP priority to different RX queues. Signed-off-by: Roger Quadros <rogerq@kernel.org> --- Changes in v4: - Use single macro AM65_CPSW_MAX_QUEUES for both TX and RX queues to simplify code - reuse am65_cpsw_get/set_per_queue_coalesce for am65_cpsw_get/set_coalesce. - return -EINVAL if unsupported tx/rx_coalesce_usecs in am65_cpsw_set_coalesce. - reverse Xmas tree declaration order fixes in cpsw_ale - Link to v3: https://lore.kernel.org/r/20240703-am65-cpsw-multi-rx-v3-0-f11cd860fd72@kernel.org Changes in v3: - code style fixes - squashed patches 5 and 6 - added comment about priority to thread mapping table. - Added Reviewed-by Simon Horman. - Link to v2: https://lore.kernel.org/r/20240628-am65-cpsw-multi-rx-v2-0-c399cb77db56@kernel.org Changes in v2: - rebase to net/next - fixed RX stall issue during iperf - Link to v1: https://lore.kernel.org/r/20240606-am65-cpsw-multi-rx-v1-0-0704b0cb6fdc@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 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.
