[ Upstream commit0d1c3de7b8] Bug description: When running "ethtool -x <if_name>" the key shows up as all zeros. When we use "ethtool -X <if_name> hfunc toeplitz hkey <some:random:key>" to set the key and then try to retrieve it using "ethtool -x <if_name>" then we return the correct key because we return the one we saved. Bug cause: We don't fetch the key from the device but instead return the key that we have saved internally which is by default set to zero upon allocation. Fix: This commit fixes the issue by initializing the key to a random value using netdev_rss_key_fill().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
