[ Upstream commit 5725bc608252050ed8a4d47d59225b7dd73474c8 ]
When using and existing adv_info instance for broadcast source it
needs to be updated to periodic first before it can be reused, also in
case the existing instance already have data hci_set_adv_instance_data
cannot be used directly since it would overwrite the existing data so
this reappend the original data after the Broadcast ID, if one was
generated.
Example:
bluetoothctl># Add PBP to EA so it can be later referenced as the BIS ID
bluetoothctl> advertise.service 0x1856 0x00 0x00
bluetoothctl> advertise on
...
< HCI Command: LE Set Extended Advertising Data (0x08|0x0037) plen 13
Handle: 0x01
Operation: Complete extended advertising data (0x03)
Fragment preference: Minimize fragmentation (0x01)
Data length: 0x09
Service Data: Public Broadcast Announcement (0x1856)
Data[2]: 0000

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.
