o uses v4 firmware instead of v3. A port will be committed to create
the bwn firmware module.
o supports B/G and LP(low power) PHYs.
o supports 32 / 64 bits DMA operations.
o tested on big / little endian machines so should work on all
architectures.
It'd not connected to the build until the firmware port is committed.

.Sh NAME
|
|
.Nm bwn
|
|
.Nd Broadcom BCM43xx IEEE 802.11b/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 siba_bwn"
|
|
.Cd "device bwn"
|
|
.Cd "device wlan"
|
|
.Cd "device wlan_amrr"
|
|
.Cd "device firmware"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_bwn_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Broadcom BCM43xx based
|
|
PCI/CardBus network adapters.
|
|
.Pp
|
|
It supports
|
|
.Cm station
|
|
and
|
|
.Cm monitor
|
|
mode operation.
|
|
Only one virtual interface may be configured at any time.
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
This driver requires firmware to be loaded before it will work.
|
|
The
|
|
.Pa ports/net/bwn-firmware-kmod
|
|
port needs to be installed before
|
|
.Xr ifconfig 8
|
|
will work.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports Broadcom BCM43xx based wireless devices, including:
