I see your point. IMHO this is ok. When the radio switch is off, it sha=
ll
be no different on every soft block modes.

Read the reply mail from Florian. This is a problem because hard blocke=
d
shall be no when the radio switch is on. Since phy0 is registered by wi=
fi
driver, I think this is not generic design.
