Miller" , Jakub Kicinski , Johan Hedberg , linux-kernel@vger.kernel.org, netdev@vger.kernel.org Sender: linux-bluetooth-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-bluetooth@vger.kernel.org This patch takes the min/max intervals and tx power optionally provided in mgmt interface, stores them in the advertisement struct, and uses them when configuring the hci requests. While tx power is not used if extended advertising is unavailable, software rotation will use the min and max advertising intervals specified by the client. This change is validated manually by ensuring the min/max intervals are propagated to the controller on both hatch (extended advertising) and kukui (no extended advertising) chromebooks, and that tx power is propagated correctly on hatch. These tests are performed with multiple advertisements simultaneously.
