[ Upstream commit7ea6cd16f1] The previous commit didn't fix the bug properly. By mistake, it replaces the pointer of the next skb in the descriptor ring instead of the current one. As a result, the two descriptors are assigned the same SKB. The error is seen during the iperf test when skb_put tries to insert a second packet and exceeds the available buffer.

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.
