Breno Leitao says: ==================== net: ethtool: add dedicated GRXRINGS driver callbacks This patchset introduces a new dedicated ethtool_ops callback, .get_rx_ring_count, which enables drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration. Number of drivers implements .get_rxnfc callback just to report the ring count, so, having a proper callback makes sense and simplify .get_rxnfc (in some cases remove it completely). This has been suggested by Jakub, and follow the same idea as RXFH driver callbacks [1]. This also port virtio_net to this new callback. Once there is consensus on this approach, I can start moving the drivers to this new callback.

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.
