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).
