NAME

       mos — Moschip MCS7730/MCS7840 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 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 chipset.

       The adapters that contain the Moschip MCS7730/MCS7830 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).
