hostapd - IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator

hostapd is a user space daemon for access point and authentication servers. 
It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP 
Authenticators, RADIUS client, EAP server, and RADIUS authentication server. 
The current version supports Linux (Host AP, madwifi, Prism54 drivers) and 
FreeBSD (net80211).

This is tested with the madwifi driver, but it should also work with some
other chipsets.  If you plan to use the madwifi driver, then uncomment the 
madwifi section in the provided config file.
