To compile this driver into the kernel, place the following lines
in  your  kernel  configuration  file: Alternatively, to load the
driver as a module at boot time,  place  the  following  line  in
if_ste_load="YES"  The  driver  provides support for PCI Ethernet
adapters and embedded controllers based on the Sundance Technolo‐
gies 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 trans‐
ceiver.  The driver supports the following  media  types:  Enable
autoselection  of the media type and options.  The user can manu‐
ally override the autoselected mode by adding  media  options  to
the  file.  Set 10Mbps operation.  The option can also be used to
select either or modes.  Set 100Mbps (Fast  Ethernet)  operation.
The  option can also be used to select either or modes.  The dri‐
ver supports the following media options: Force full duplex oper‐
ation.  Force half duplex operation.   For  more  information  on
configuring  this  device, see The driver supports Sundance Tech‐
nologies ST201 based Fast Ethernet  adapters  and  embedded  con‐
trollers  including:  D-Link  DFE-530TXS  D-Link DFE-550TX D-Link
DFE-580TX The following variables are available as both variables
and tunables: Maximum number of time to delay RX interrupts.  The
valid range is 0 to 209712 in units of 1us, the  default  is  150
(150us).   The value 0 effectively disables the RX interrupt mod‐
eration.  The resolution of timer is about 3.2us so finer  tuning
than 3.2us wouldn't be available.  The interface does not need to
be brought down and up again before a change takes effect.  A fa‐
tal  initialization  error  has occurred.  A fatal initialization
error has occurred.  The device has  stopped  responding  to  the
network,  or  there is a problem with the network connection (ca‐
ble).  The driver failed to allocate an  mbuf  for  the  receiver
ring.   The driver failed to allocate an mbuf for the transmitter
ring when allocating a pad buffer or  collapsing  an  mbuf  chain
into a cluster.  This message applies only to adapters which sup‐
port  power  management.   Some  operating systems place the con‐
troller 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 condition 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  net‐
work  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 operating system.  If
you power down your system prior to booting the  card  should  be
configured  correctly.   The  device driver first appeared in The
