Implement RINGS_GET request to get ring sizes of a network device. These are traditionally available via ETHTOOL_GRINGPARAM ioctl request. Omit attributes for ring types which are not supported by driver or device (zero reported for maximum). v2: (all suggested by Jakub Kicinski) - minor cleanup in rings_prepare_data() - more descriptive rings_reply_size() - omit attributes with zero max size Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@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 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.
