Daniel Winkler ff02db13e9 Bluetooth: Allow scannable adv with extended MGMT APIs
An issue was found, where if a bluetooth client requests a broadcast
advertisement with scan response data, it will not be properly
registered with the controller. This is because at the time that the
hci_cp_le_set_scan_param structure is created, the scan response will
not yet have been received since it comes in a second MGMT call. With
empty scan response, the request defaults to a non-scannable PDU type.
On some controllers, the subsequent scan response request will fail due
to incorrect PDU type, and others will succeed and not use the scan
response.

This fix allows the advertising parameters MGMT call to include a flag
to let the kernel know whether a scan response will be coming, so that
the correct PDU type is used in the first place. A bluetoothd change is
also incoming to take advantage of it.

To test this, I created a broadcast advertisement with scan response
data and registered it on the hatch chromebook. Without this change, the
request fails, and with it will succeed.

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.
