---help---
Shared driver code for IEEE 802.11b wireless cards based on
Intersil Prism2/2.5/3 chipset. This driver supports so called
Host AP mode that allows the card to act as an IEEE 802.11
access point.
In addition, this includes generic IEEE 802.11 code, e.g., for
WEP/TKIP/CCMP encryption that can be shared with other drivers.
See <http://hostap.epitest.fi/> for more information about the
Host AP driver configuration and tools. This site includes
information and tools (hostapd and wpa_supplicant) for WPA/WPA2
support.
This option includes the base Host AP driver code that is shared by
different hardware models. You will also need to enable support for
PLX/PCI/CS version of the driver to actually use the driver.
The driver can be compiled as a module and it will be called
"hostap.ko".
