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.
