    iwlagn: clean up & autodetect statistics · 0da0e5bf
    Johannes Berg authored
    There's no need to keep both normal and BT statistics
    versions around all the time in memory when we only
    use a subset of both. So keep only the subsets that
    we need in memory, depending on the debug config).
    Also, in doing so, we can remove all the calls to
    iwl_bt_statistics() in the driver as we'll just
    access the copied statistics now.
    Finally, also remove this call from the one place
    where it might still be needed and automatically
    detect what kind of statistics the device is sending
    based on their size. This way, we don't need to keep
    track of which devices do what any more, which is
    good since this is subject to change based on the
    ucode version (as some ucode even for non-BT devices
    will in fact use BT statistics).
    Warn upon encountering a statistics command from the
    ucode that isn't known, so we will find such issues
    earlier in the future.
