[ Upstream commit7d2c89b325] GSO should not merge page pool recycled frames with standard reference counted frames. Traditionally this didn't occur, at least not often. However as we start looking at adding support for wireless adapters there becomes the potential to mix the two due to A-MSDU repartitioning frames in the receive path. There are possibly other places where this may have occurred however I suspect they must be few and far between as we have not seen this issue until now.

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.
