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