config HOSTAP
tristate "IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP)"
depends on NET_RADIO
---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".
config HOSTAP_WEP

depends on HOSTAP
select CRYPTO
---help---
Software implementation of IEEE 802.11 TKIP encryption.
This can be compiled as a modules and it will be called

config HOSTAP_CCMP
tristate "IEEE 802.11 CCMP encryption"
depends on HOSTAP
select CRYPTO
---help---
Software implementation of IEEE 802.11 CCMP encryption.
This can be compiled as a modules and it will be called
"hostap_crypt_ccmp.ko".
config HOSTAP_FIRMWARE

depends on HOSTAP
---help---
Configure Host AP driver to include support for firmware image
download. Current version supports only downloading to volatile, i.e.,
RAM memory. Flash upgrade is not yet supported.
Firmware image downloading needs user space tool, prism2_srec. It is
available from http://hostap.epitest.fi/.
config HOSTAP_PLX

PCI adaptors.
"Host AP support for Prism2/2.5/3 IEEE 802.11b" is required for this
driver and its help text includes more information about the Host AP
driver.
The driver can be compiled as a module and will be named
"hostap_plx.ko".
config HOSTAP_PCI
