36 .Nd Broadcom BCM430x/4318 IEEE 802.11b/g wireless network driver
38 To load the driver as a module at boot time, place the
40 .Pa /boot/loader.conf :
41 .Bd -literal -offset indent
47 driver provides support for Broadcom BCM430x/4318 wireless network adapters.
48 For more information on configuring this device, see
51 The following per-interface variables are implemented in the
56 .Bl -tag -width ".Va txpwr_calib"
60 Channel dwell time during scan (msec).
64 Number of ticks before LED enters idle state.
68 Enable software TX power calibration.

93 The firmware files have to reside in
95 and will be loaded when the interface is brought up.
113 driver first appeared in
119 driver was written by
