When the firmware rejects a frame (because station become asleep or disconnected), the frame is re-queued in mac80211. However, the re-queued frame was 8 bytes longer than the original one (the size of the ICV for the encryption). So, when mac80211 try to send this frame again, it is a little bigger than expected. If the frame is re-queued secveral time it end with a skb_over_panic because the skb buffer is not large enough. Note it only happens when device acts as an AP and encryption is enabled. This patch more or less reverts the commit049fde1304("staging: wfx: drop useless field from struct wfx_tx_priv").

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.
