Currently, when a non-DFS channel is brought up and the bandwidth is expanded from 80 MHz to 160 MHz, where the primary 80 MHz is non-DFS and the secondary 80 MHz consists of DFS channels, radar detection fails if radar occurs in the secondary 80 MHz. When the channel is switched from 80 MHz to 160 MHz, with the primary 80 MHz being non-DFS and the secondary 80 MHz consisting of DFS channels, the radar required flag in the channel switch parameters is set to true. However, when using a reserved channel context, it is not updated in sdata, which disables radar detection in the secondary 80 MHz DFS channels. Update the radar required flag in sdata to fix this issue when using a reserved channel context.

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 reStructuredText 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.
