Support setting RSS hash function / algo via ethtool Netlink. Like IOCTL we don't validate that the function is within the range known to the kernel. The drivers do a pretty good job validating the inputs, and the IDs are technically "dynamically queried" rather than part of uAPI. Only change should be that in Netlink we don't support user explicitly passing ETH_RSS_HASH_NO_CHANGE (0), if no change is requested the attribute should be absent. The ETH_RSS_HASH_NO_CHANGE is retained in driver-facing API for consistency (not that I see a strong reason for it).

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.
