First of all please don't send private emails on topics that can be
discussed in public. I've included linux-bluetooth in CC where I hope

The HCI_AUTO_OFF flag is a purely kernel-side feature without any user
space interface. It gets automatically cleared when the kernel completes
the initial setup/init routine of the controller.
