Miller" , Jakub Kicinski , Johan Hedberg , linux-kernel@vger.kernel.org, netdev@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-bluetooth@vger.kernel.org This patch adds code to handle the active scan during interleave scan. The interleave scan will be canceled when users start active scan, and it will be restarted after active scan stopped.
