32 .Nd Broadcom BCM43xx IEEE 802.11b/g wireless network driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
41 .Cd "device wlan_amrr"
45 Alternatively, to load the driver as a
46 module at boot time, place the following line in
48 .Bd -literal -offset indent
54 driver provides support for Broadcom BCM43xx based
55 PCI/CardBus network adapters.
62 Only one virtual interface may be configured at any time.
63 For more information on configuring this device, see
66 This driver requires firmware to be loaded before it will work.
68 .Pa ports/net/bwn-firmware-kmod
69 port needs to be installed before
72 Most cases you need to use bwn_v4_ucode module but if you are a
73 LP (low power) PHY user please uses bwn_v4_lp_ucode module.
77 driver supports Broadcom BCM43xx based wireless devices, including:

96 because the v4 version of the firmware does not support these chips.
97 The newer firmware is too big to fit into these old chips.

118 prompt before booting the kernel or stored in
120 .Bl -tag -width indent
121 .It Va hw.bwn.msi_disable
122 This tunable disables MSI support on the hardware.
123 The default value is 0.
125 This tunable enables DMA operations on the hardware.
126 If the value is 0, PIO mode would be used.
