mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

README
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.
