Declare this function allows us to use customized scanning policy. By doing so we can be more time efficient on each scan. In order to make existing coex mechanism work as usual, firmware notifies driver on each channel switch event, then decide antenna ownership based on the current channel/band. Do note that this new mechanism affects throughput more than the sw_scan we used to have, but the overall average throughput is not affected since each scan take less time. Since the firmware size is limited, we only support probe requests with custom IEs length under 128 bytes for now, if any user space tools requires more than that, we'll introduce related changes afterwards. For backward compatibility, we fallback to sw_scan when using older firmware that does not support this feature.

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.
