Subject: [PATCH v6 1/5] Bluetooth: Add helper to set adv data
Date: Mon, 30 Nov 2020 14:57:40 -0800	[thread overview]
Message-ID: <20201130145609.v6.1.I5f4fa6a76fe81f977f78f06b7e68ff1c76c6bddf@changeid> (raw)
In-Reply-To: <20201130225744.3793244-1-danielwinkler@google.com>

We wish to handle advertising data separately from advertising
parameters in our new MGMT requests. This change adds a helper that
allows the advertising data and scan response to be updated for an
existing advertising instance.
