Broadcom controllers present on Apple Silicon devices use the upper
8 bits of the event type in the LE Extended Advertising Report for
the channel on which the frame has been received.
These bits are reserved according to the Bluetooth spec anyway such that
we can just drop them to ensure that the advertising results are parsed
correctly.
The following excerpt from a btmon trace shows a report received on
channel 37 by these controllers:

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.
