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).
HARDWARE
Adapters supported by the mos driver include:
