[ Upstream commit12fc512f57] xdp_return_frame releases the frame. It leads to releasing the page, so it's not allowed to access xdpi.xdpf->len after that, because xdpi.xdpf is at xdp->data_hard_start after convert_to_xdp_frame. This patch moves the memory access to precede the return of the frame.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
