[ Upstream commit 1d155dfdf5 ]
In bug report [0] a warning in r8169 driver was reported that was
caused by an invalid GSO SKB (gso_type was 0). See [1] for a discussion
about this issue. Still the origin of the invalid GSO SKB isn't clear.
It shouldn't be a network drivers task to check for invalid GSO SKB's.
Also, even if issue [0] can be fixed, we can't be sure that a
similar issue doesn't pop up again at another place.
Therefore let gso_features_check() check for such invalid GSO SKB'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.
