MOS(4) FreeBSD Kernel Interfaces Manual MOS(4) 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 fol- lowing: Delock 61147 Sitecom LN-030 Syba SY-U2LAN All adapters operate with either USB 1.x or USB 2.0 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 hostname.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). DIAGNOSTICS mos0: watchdog timeout A packet was queued for transmission and a trans- mit command was issued, however the device failed to acknowledge the transmission before a timeout expired. mos0: no memory for rx list The driver failed to allocate an mbuf for the receiver ring.
