NAME
mos -- MosChip MCS7730/7830/7832 10/100 USB Ethernet device
SYNOPSIS
mos* at uhub?
DESCRIPTION
The mos driver provides support for USB Ethernet adapters based on the
MosChip MCS7730, MCS7830, and MCS7832 USB 2.0 chipsets, including the
following:
Delock 61147
Sitecom LN-030
Syba SY-U2LAN
All adapters operate with either USB 1.x, 2.0, or 3.x controllers, though
performance with 1.x controllers is limited since the USB 1.x standard
specifies a maximum transfer speed of 12Mbps. Users with USB 1.x con-
trollers should therefore not expect to actually achieve 100Mbps speeds
with these devices.
A 64-bit multicast hash table is supported, single perfect filter entry
for the station address, all-multicast mode, and promiscuous mode. Pack-
ets are received and transmitted over separate USB bulk transfer end-
points.
The mos driver supports the following media types:
autoselect Enable autoselection of the media type and options (this is
the default). The user can manually override the autose-
lected mode by adding media options to the appropriate
ifconfig.if(5) file.
10baseT Set 10Mbps operation.
100baseTX Set 100Mbps (Fast Ethernet) operation.
The mos driver supports the following media options:
full-duplex Force full-duplex operation.
half-duplex Force half-duplex operation.
For more information on configuring this device, see ifconfig(8).
