.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.
Language cleanup. Noticed during wblock's manpage walkthrough at BSDCan 2015.

In most cases the
.Pa bwn_v4_ucode
kernel module from the port should be used.
However, if an LP (low power) PHY is being used, the
.Pa bwn_v4_lp_ucode
module should be used.
