# acx100 driver, available at http://acx100.sourceforge.net

tristate "Texas Instruments ACX100/ACX111 (TNETW1xxx) cards"
depends on NET_RADIO && PCI && !SMP
default n
---help---
A driver for almost all wireless cards based on Texas Instruments'
very poorly vendor-supported ACX100 wireless network chip
(except for USB and Compact Flash implementations, which are
both extremely rare -- semi-stable USB support exists for
2.4.x, but 2.6.x USB support is not quite functional at all
yet). Almost working ACX111 support is in the driver, but it's
still not quite working yet, due to many changes compared to
the ACX100. This driver supports standard Linux wireless
extensions to a very wide extent.
Currently this driver still is a bit experimental. We're still not
totally sure about the status of WEP support. Many situations
should work, but it might still not work properly or fail sometimes.
Also, SMP appears to be problematic (locking issues).
Furthermore, associating with some access points might still be
problematic due to strict 802.11 compliance checks in their
firmware.
Master mode support (aka HostAP) has not been implemented completely
yet, but at least it can be configured now. The non-standard 4x
mode (aka "44Mbps") is NOT supported yet and will need several
driver changes.
You can use the driver compiled in the kernel or as a module:
the module will be called acx_pci.
This driver needs a firmware to work and since firmware image and
radio image can't be provided with this driver, you need to find
it by yourself (please read the README provided with the 'acx100'
source package).
The driver expects the firmware files to be placed in the
firmware directory /usr/share/acx/ by default. If you intend to
use a custom firmware directory, then in case you're using a
driver module, you should specify/configure the module parameter
firmware_dir=[full path to the firmware directory], and in case
you are using the builtin driver, you need to give the kernel
boot parameter acx_firmware_dir=[full path to the firmware directory].
The 'acx100' project page is at <http://acx100.sourceforge.net>.
You can find a useful HOWTO for Mandrake, Slackware, Red Hat and
Debian (Knoppix) at <http://www.houseofcraig.net/acx100_howto.php>.
You will very likely also need the Wireless Tools in order to
configure your card and to make /etc/pcmcia/wireless.opts work:

The Linux hotplug package is required for automatic setup of
CardBus cards and for proper ACX100 USB card operations.
