.Sh NAME
.Nm acx
.Nd Texas Instruments ACX100/ACX111 IEEE 802.11a/b/g wireless network driver
.Sh SYNOPSIS
To compile this driver into the kernel, place the following lines in
your kernel configuration file:
.Bd -ragged -offset indent
.Cd "device acx"
.Cd "device wlan"
.Cd "device wlan_ratectl_onoe"
.Cd "device wlan_ratectl_amrr"
.Ed
.Pp
Alternatively, to load the driver as a module at boot time, place the
following line in
.Pa /boot/loader.conf :
.Bd -literal -offset indent
if_acx_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for Texas Instruments TNETW1100/TNETW1100B (ACX100)
and TNETW1130 (ACX111) based PCI/CardBus network adapters.
.Pp
The ACX100A and ACX100B are first generation 802.11b devices
from TI.
The ACX111 is a second generation device which supports 802.11b/g
and in some cases 802.11a.
.Pp
By default, the
.Nm
driver configures the adapter for BSS operation (infrastructure mode).
This mode requires the use of an access point.
In addition, IBSS operation (adhoc mode) is also supported.
For more information on configuring this device, see
.Xr ifconfig 8 .
.Ss MIB Variables
The following per-interface variables are implemented in the
.Va hw.acx Ns Em X
branch of the
.Xr sysctl 3
MIB.
.Bl -tag -width ".Va combined_radio_fw"
.It Va msdu_lifetime
MSDU life time.
.It Va long_retry_limit
Long retry limit.
.It Va scan_dwell
Channel dwell time during scanning (unit: milliseconds)
.It Va combined_radio_fw
The base and radio firmwares are combined in one image file.
By default,
it is set to 1 for ACX111 parts and 0 for ACX100A and ACX100B parts.
.It Va free_fw
Set to non-zero value to free the loaded firmwares.
This does not affect a running device.
Firmwares will be reloaded from
.Pa /etc/firmware/acx
when device is brought up next time.

.Sh HARDWARE
The following cards are among those supported by the
.Nm
driver:

.Sh FILES
The firmware for the adapter is not shipped with
.Dx
and must be obtained separately.
An archive with firmware files that are known to work can be found at:
.Bd -literal -offset indent
http://leaf.dragonflybsd.org/~sephe/acx/acx_fw.tbz
.Ed
.Pp
The firmware files have to reside in
.Pa /etc/firmware/acx
and will be loaded when the interface is brought up.

.Sh HISTORY
The
.Nm
driver first appeared in
.Dx 1.5 .
.Sh AUTHORS
.An -nosplit
The
.Nm
driver was written by
.An Sepherosa Ziehau .
The manual page was written by
.An Sascha Wildner .
Both are based on the
.Pa http://wlan.kewl.org
project team's original code.
.Pp
The hardware specification was reverse engineered by the good folks at
.Pa http://acx100.sourceforge.net .
Without them this driver would not have been possible.
