In the case where the hardware gives us a null Rx descriptor, it is theoretically possible that we could call one of our skb-construction functions with no data pointer, which would cause a panic. In real life, this will never happen - we only get null RX descriptors as the final descriptor in a chain of otherwise-valid descriptors. When this happens, the skb will be extant and we'll just call ice_add_rx_frag(), which can deal with empty data buffers. Unfortunately, Coverity does not have intimate knowledge of our hardware, so we must add a check here.

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.
