When we flush stations, we first take them off the list and then destroy them one by one. If we do the different mode recalculations while destroying them, we cause the following scenario: - STA 1 has 80 MHz - min chanctx width is now 80 MHz - STA 2 has 80 MHz - empty STA list - destroy STA 2 - recalc min chanctx width -> results in 20 MHz as the STA list is already empty This is broken, since as far as the driver is concerned STA 1 still exists at this point, and this causes issues at least with iwlwifi. Fix - and also optimize - this by doing the recalc of min chanctx width (and also P2P PS) only after all the stations were removed.

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.
