Could not read wlan PDA. This requires PRISM2_DOWNLOAD_SUPPORT definition in
driver/module/hostap_config.h.

# cat ./hostap_config.h |grep PRISM2_DOWNLOAD_SUPPORT
/* #define PRISM2_DOWNLOAD_SUPPORT */
#if !defined(PRISM2_DOWNLOAD_SUPPORT) && defined(CONFIG_HOSTAP_FIRMWARE)
#define PRISM2_DOWNLOAD_SUPPORT
#ifdef PRISM2_DOWNLOAD_SUPPORT
#endif /* PRISM2_DOWNLOAD_SUPPORT */
