34 To compile this driver into the kernel, add the following lines to the kernel
36 .Bd -ragged -offset indent
40 .Cd "device bhndb_pci"
45 .Cd "device wlan_amrr"
49 To load the driver as a module at boot, add the following lines to

57 driver provides support for Broadcom BCM43xx based
58 PCI/CardBus network adapters.
65 Only one virtual interface may be configured at any time.

72 port needs to be installed before
77 kernel module from the port should be used.
78 However, if an LP (low power) PHY is being used, the
80 module should be used.

129 This tunable enables DMA operations on the hardware.
