I am unaware that wpa_supplicant is now part of the base system and
continued to use the cvs-ports wpa_supplicant v0.3.8.  Thanks for pointing
this out.

I have rebuilt the base wpa_supplicant from source and enable EAP-TTLS
support.  Now sp_scan=2 option does not cause core dump, but wpa_supplicant
has problem connecting to the AP using the non-broadcast SSID:

	wpa_driver_bsd_associate: ssid 'employee' wpa ie len 24 pairwise 2
group 2 key mgmt 0
	wpa_driver_bsd_associate: set PRIVACY 1
	ioctl[SIOCS80211, op 21, len 42]: Invalid argument
	Association request to the driver failed

I am cross posting this question to both hostap and freebsd.  If this is
just a driver issue, I will pursue this on the freebsd forum.
