    DESCRIPTION

         The ste driver provides support for PCI Ethernet adapters and embedded
         controllers based on the Sundance Technologies ST201 PCI Fast Ethernet
         controller chip.
    
         The Sundance ST201 uses bus master DMA and is designed to be a 3Com
         Etherlink XL workalike.  It uses the same DMA descriptor structure and is
         very similar in operation, however its register layout is different.  The
         ST201 has a 64-bit multicast hash filter and a single perfect filter
         entry for the station address.  It supports both 10 and 100Mbps speeds in
         either full or half duplex using an MII transceiver.
    
         The ste driver supports the following media types:
    
         autoselect            Enable autoselection of the media type and options.
                               The user can manually override the autoselected
                               mode by adding media options to the /etc/rc.conf
                               file.
    
         10baseT/UTP           Set 10Mbps operation.  The mediaopt option can also
                               be used to select either full-duplex or half-duplex
                               modes.
    
         100baseTX             Set 100Mbps (Fast Ethernet) operation.  The
                               mediaopt option can also be used to select either
                               full-duplex or half-duplex modes.
    
         The ste 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).
    
    
    

    HARDWARE

         The ste driver supports Sundance Technologies ST201 based Fast Ethernet
         adapters and embedded controllers including:
    
         ?   D-Link DFE-530TXS
         ?   D-Link DFE-550TX
         ?   D-Link DFE-580TX
         ste%d: couldn't map ports/memory  A fatal initialization error has
         occurred.
    
         ste%d: couldn't map interrupt  A fatal initialization error has occurred.
    
         ste%d: watchdog timeout  The device has stopped responding to the net-
         work, or there is a problem with the network connection (cable).
    
         ste%d: no memory for rx list  The driver failed to allocate an mbuf for
         the receiver ring.
    
         ste%d: no memory for tx list  The driver failed to allocate an mbuf for
         the transmitter ring when allocating a pad buffer or collapsing an mbuf
         chain into a cluster.
    
         ste%d: chip is in D3 power state -- setting to D0  This message applies
         only to adapters which support power management.  Some operating systems
         place the controller in low power mode when shutting down, and some PCI
         BIOSes fail to bring the chip out of this state before configuring it.
         The controller loses all of its PCI configuration in the D3 state, so if
         the BIOS does not set it back to full power mode in time, it will not be
         able to configure it correctly.  The driver tries to detect this condi-
         tion and bring the adapter back to the D0 (full power) state, but this
         may not be enough to return the driver to a fully operational condition.
         If you see this message at boot time and the driver fails to attach the
         device as a network interface, you will have to perform a second warm
         boot to have the device properly configured.
    
         Note that this condition only occurs when warm booting from another oper-
         ating system.  If you power down your system prior to booting FreeBSD,
         the card should be configured correctly.
