wireless/wapi: wpa_driver_wext_associate() now accepts a configuration parameter that can be used to specify the wireless properties. nshlib: NSH now has configuration options to select the wireless properties. It builds the configuration structure and passes this to wpa_driver_wext_associate() so that it will setwork the network as configured.
