NAME
     mos — Moschip MCS7730/MCS7830/MCS7832 USB Ethernet driver


SYNOPSIS
     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device uhci
           device ohci
           device ehci
           device usb
           device miibus
           device uether
           device mos

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           if_mos_load="YES"


DESCRIPTION
     The mos driver provides support for USB Ethernet adapters based on the Moschip
     MCS7730/MCS7830/MCS7832 chipset.

     The adapters that contain the Moschip MCS7730/MCS7830/MCS7832 chipset will operate at
     100Base-TX and full-duplex.

     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.

     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.

     For more information on configuring this device, see ifconfig(8).
