    I was referring to hci_ll as to the line discipline driver, not the
    line discipline itself.

    The thing is, there are different Bluetooth combo chips which use HCI
    to encapsulate commands to the sub-chips behind, and there's also the
    implementation for TI chip doing that which is in the mainline. So
    instead of keeping reinventing the wheel, I think it's fairly
    beneficial for everything if we finally agree on something that works
    for all the combo chips of the type.
