This is a Linux driver for wireless LAN cards based on Intersil's Prism2/2.5/3 chipset. The driver supports a so called Host AP mode, i.e., it takes care of IEEE 802.11 management functions in the host computer and acts as an access point. This does not require any special firmware for the wireless LAN card. In addition to this, it has support for normal station operations in BSS and possible also in IBSS. The station mode supports WPA when used with accompanied tools, wpa_supplicant.
