+.Sh NAME
+.Nm kue
+.Nd "Kawasaki LSI KL5KUSB101B USB Ethernet 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 uhci"
+.Cd "device ohci"
+.Cd "device usb"
+.Cd "device kue"
+.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_kue_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB Ethernet adapters based on the Kawasaki
+LSI KL5KLUSB101B chipset.
+.Pp
+The KL5KLUSB101B supports a 128-entry multicast filter, single perfect
+filter entry for the station address and promiscuous mode.
+Packets are
+received and transmitted over separate USB bulk transfer endpoints.
+.Pp
+The Kawasaki chipset supports only 10Mbps half-duplex mode, hence there
+are no
+.Xr ifmedia 4
+modes to select.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh HARDWARE
