That error actually means nothing and I believe the log message has been
removed in recent supplicant versions.  It simply means that the driver
doesn't support some of the random ioctls that the supplicant tries, but
most of the time, that's not a problem.

What you can do for the time being is increase the association timeout
(which gets lowered to like 5 seconds if that message is printed because
the driver returned -1 from wpa_drv_associate()), and see if the card
does in fact associate after 10 or 15 seconds.  That is a useful point
of debugging information.
