Vladimir Oltean says: ==================== net: Convert dsa_master_ioctl() to netdev notifier This is preparatory work in order for Maxim Georgiev to be able to start the API conversion process of hardware timestamping from ndo_eth_ioctl() to ndo_hwtstamp_set(): https://lore.kernel.org/netdev/20230331045619.40256-1-glipus@gmail.com/ In turn, Maxim Georgiev's work is a preparation so that Köry Maincent is able to make the active hardware timestamping layer selectable by user space. https://lore.kernel.org/netdev/20230308135936.761794-1-kory.maincent@bootlin.com/ So, quite some dependency chain. Before this patch set, DSA prevented the conversion of any networking driver from the ndo_eth_ioctl() API to the ndo_hwtstamp_set() API, because it wanted to validate the hwtstamping settings on the DSA master, and it was only coded up to do this using the old API. After this patch set, a new netdev notifier exists, which does not depend on anything that would constitute the "soon-to-be-legacy" API, but rather, it uses a newly introduced struct kernel_hwtstamp_config, and it doesn't issue any ioctl at all, being thus compatible both with ndo_eth_ioctl(), and with the not-yet-introduced, but now possible, ndo_hwtstamp_set(). ==================== 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.
