Sorry if I was'nt clear enough, but I want to enhance the basic
association process by adding extra IEs and I found some references on
how to add IEs in the WPA supplicant code. driver_hostap.c uses a
ioctl which eventually calls prism2_ioctl_set_generic_element in
hostap_ioctl.c which adds the generic Information Element.

So my first question was how to make sure a certain IE was added to
e.g. the association request (response) sent to a AP (STA).

Does this means that the supplied IE will be added to the next
management frame?
