The firmware is able to filter beacons and send a notification if one or
multiple beacons are not received. Note that it send this notification
only once. Only if it receive beacons gain, it send a new notification.
Currently, the driver handle the connection loss itself (see
wfx_cqm_bssloss_sm()). It send null frames and watch the answers.
This patch fixes all this mess:
- settle firmware to send a notification on the first beacon loss
- call ieee80211_beacon_loss() and let mac80211 handle all the process
- since we do have notification for each beacon loss, add a period
task that call ieee80211_beacon_loss() until we receive "REGAIN"
notification.
Thus, we can drop the ugly wfx_cqm_bssloss_sm() and
wfx_bss_params_work().

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.
