Szymon Janc 3d23669649 Bluetooth: Workaround directed advertising bug in Broadcom controllers
[ Upstream commit 4c371bb95cf06ded80df0e6139fdd77cee1d9a94 ]

It appears that some Broadcom controllers (eg BCM20702A0) reject LE Set
Advertising Parameters command if advertising intervals provided are not
within range for undirected and low duty directed advertising.

Workaround this bug by populating min and max intervals with 'valid'
values.

< HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15
        Min advertising interval: 0.000 msec (0x0000)
        Max advertising interval: 0.000 msec (0x0000)
        Type: Connectable directed - ADV_DIRECT_IND (high duty cycle) (0x01)
        Own address type: Public (0x00)
        Direct address type: Random (0x01)
        Direct address: E2:F0:7B:9F:DC:F4 (Static)
        Channel map: 37, 38, 39 (0x07)
        Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00)
> HCI Event: Command Complete (0x0e) plen 4
      LE Set Advertising Parameters (0x08|0x0006) ncmd 1
        Status: Invalid HCI Command Parameters (0x12)

README

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.
