HostAP
HostAP is a IEEE 802.11 device driver for Linux. It works with cards using the obsolete Conexant Prism 2/2.5/3 chipset and supports Host AP mode, which allows a WLAN card to perform all the functions of a wireless access point.
The driver code was written by Jouni Malinen, hired by Atheros in 2008, and was included into the main kernel tree in Linux 2.6.14.
As of November 2016, HostAP is officially obsolete in the Linux kernel.
