+.Sh NAME
+.Nm mos
+.Nd Moschip MCS7730/MCS7840 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 miibus"
+.Cd "device mos"
+.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_mos_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB Ethernet adapters based on the 
+Moschip MCS7730/MCS7830 chipset.
+.Pp
+The adapters that contain the Moschip MCS7730/MCS7830 chipset
+will operate at 100Base-TX and full-duplex.
+.Pp
+The Moschip contains a 10/100
+Ethernet MAC with MII interface and is designed to work with both
+Ethernet and HomePNA transceivers.
+Although designed to interface with
+100Mbps peripherals, this only works with USB 2.0. The existing USB 1.0
+standard specifies a maximum transfer speed of 12Mbps.
+USB 1.0 Users should therefore not expect to actually achieve 100Mbps speeds
+with these devices.
+.Pp
+The Moschip supports a 64-bit multicast hash table, single perfect
+filter entry for the station address and promiscuous mode.
+Packets are
+received and transmitted over separate USB bulk transfer endpoints.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
