mos — Moschip MCS7730/MCS7830/MCS7832 USB Ethernet driver
Contents
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).
Hardware
Adapters supported by the mos driver include:
• Sitecom LN030
History
The mos device driver first appeared in FreeBSD 8.2.
