frag_timer will be created & initialized for stations when
they associate and will be deleted during every key installation
while flushing old fragments.
For AP interface self peer will be created and Group keys
will be installed for this peer, but there will be no real
Station entry & hence frag_timer won't be created and
initialized, deleting such uninitialized kernel timers causes below
warnings and backtraces printed with CONFIG_DEBUG_OBJECTS_TIMERS
enabled.

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.
