The firmware is offering features such as ARP offload, for which
firmware crafts its own (QoS)packets without waking up the host.
Point is that the sequence numbers generated by the firmware are
not in sync with the host mac80211 layer and can cause packets
such as firmware ARP reponses to be dropped by the AP (too old SN).
To fix this we need to let the firmware manages the sequence
numbers by its own (except for QoS null frames). There is a SN
counter for each QoS queue and one global/baseline counter for
Non-QoS.

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.
