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).
