Do not attempt association until directed to do so by a user space
application. In particular, this avoids race conditions with
NetworkManager association state.

Or not, just thought that since the rest two lines below do it, but
actually pointless.

Though for completeness, maybe associate = 0; ?

Cards shouldn't be associating automatically with anything until told to
do so to a specific SSID or specific BSSID/SSID combination, otherwise
it's a security risk. The 3 people out in the middle of nowhere with
one unencryped access point who may want this functionality should be
turning it on manually because they are clearly more technically able
than most.
