The tulip driver has a debugging method over ioctl built-in, but it does not actually check the command type, which may end up leading to random behavior when trying to run other ioctls on it. Change the driver to use ndo_siocdevprivate and limit the execution further to the first private command code. If anyone still has tools to run these debugging commands, they might have to be patched for it if they pass different ioctl command. The function has existed in this form since the driver was merged in Linux-1.1.86. Cc: linux-parisc@vger.kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de> 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.
