[ Upstream commit86af062f40] Currently MBSSID parameters in struct ieee80211_bss_conf are not reset upon connection. This could be problematic with some drivers in a scenario where the device first connects to a non-transmit BSS and then connects to a transmit BSS of a Multi BSS AP. The MBSSID parameters which are set after connecting to a non-transmit BSS will not be reset and the same parameters will be passed on to the driver during the subsequent connection to a transmit BSS of a Multi BSS AP. For example, firmware running on the ath11k device uses the Multi BSS data for tracking the beacon of a non-transmit BSS and reports the driver when there is a beacon miss. If we do not reset the MBSSID parameters during the subsequent connection to a transmit BSS, then the driver would have wrong MBSSID data and FW would be looking for an incorrect BSSID in the MBSSID beacon of a Multi BSS AP and reports beacon loss leading to an unstable connection. Reset the MBSSID parameters upon every connection to solve this problem.

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.
