+	Allow Host AP driver to write firmware images to the non-volatile
+	card memory, i.e. flash memory that survives power cycling.
+	Enable this option if you want to be able to change card firmware
+	permanently.
+
+	Firmware image downloading needs a user space tool, prism2_srec.
+	It is available from http://hostap.epitest.fi/.
