mos -- MosChip MCS7730/7830/7832 10/100 USB Ethernet device
mos* at uhub?
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).
See usbnet(4) for diagnostics.
