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, normal station operations in BSS (infrastructure) and in IBSS (ad hoc). Current version of the Host AP driver and tools supports WPA in AP (Authenticator) and client (Supplicant) modes.

Intersil's station firmware for Prism2/2.5/3 chipset supports a so called Host AP mode in which the firmware takes care of time critical tasks like beacon sending and frame acknowledging, but leaves other management tasks to host computer driver.

Here are some key features of "hostap":
This driver implements basic functionality needed to initialize and configure Prism2/2.5/3-based cards, to send and receive frames, and to gather statistics. In addition, it includes an implementation of following IEEE 802.11 functions:
authentication (and deauthentication).
association (reassociation, and disassociation).
data transmission between two wireless stations.
power saving (PS) mode signaling and frame buffering for PS stations.
The driver has also various features for development debugging and for researching IEEE 802.11 environments like access to hardware configuration records, I/O registers, and frames with 802.11 headers.

What's New in This Release:
fixed background scans (iwlist wlan0 scan) not to break data connection when in host_roaming 2 mode (e.g., when using wpa_supplicant)
fixed beacon frame when moving from monitor mode to master mode (workaround for firmware bug that left IBSS IE in the Beacon frames)
