>From 'IEEE Std 802.11-2020 section 11.3.4.1': If STA A in an infrastructure BSS receives a Class 2 or Class 3 frame from STA B that is not authenticated with STA A (i.e., the state for STA B is State 1), STA A shall discard the frame. If the frame has an individual address in the Address 1 field, the MLME of STA A shall send a Deauthentication frame to STA B. When data frames from unassociated stations are received by an AP, the AP is supposed to send a deauthentication/disassociation frame with reason code "Class 2 frame received from nonauthenticated STA" or "Class 3 frame received from nonassociated STA". But ath12k AP doesn't send deauthentication/disassociation frames, when it receives data frames from unassociated stations. The ath12k driver drops the data frames from unassociated station and the upper layer(mac80211/hostapd) is not aware of such event. Hence deauthentication/disassociation frame is not sent to that particular station by the AP. To address this issue, allow the data frames from the unassociated stations to reach mac80211 so that mac80211 can send NL80211_CMD_UNEXPECTED_FRAME event to userspace(hostapd) and hostapd upon receiving the event will send the deauthentication/disassociation frame with proper reason code. The data frame from unassociated stations gets dropped in mac80211.

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.
