    Do you want to associate to an AP when your kernel boots,
    _before_ any iwconfig had a chance to configure anything?
    That's strange.

    My position is that wifi drivers must start up in an "OFF" mode.
    Do not send anything. Do not join APs or start IBSS.
    Thus, no need to load fw in early boot.

    Driver may load firmware and start actively doing something
    only when iwconfig gets executed and thus driver is
    instructed what to do.

    Some drivers currently do not act this way, and thus
    less advanced users may unknowingly run a wireless STA
    (or worse, an AP!) on their notebook for years, interfering
    with neighbors and/or violating local regulations (there are
    countrles where 802.11 use needs licensing).
