     ste - Sundance Technologies ST201 Fast Ethernet driver

SYNOPSIS    [Toc]    [Back]

     ste* at pci? dev ? function ?

DESCRIPTION    [Toc]    [Back]

     The ste driver provides support for  PCI  Ethernet  adapters
and embedded
     controllers  based  on  the  Sundance Technologies ST201 PCI
fast Ethernet
     controller chip.  This includes the D-Link DFE-550TX.

     The Sundance ST201 uses bus master DMA and is designed to be
a 3Com
     EtherLink  XL  work-alike.   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 hostname.if(5) file.

     10baseT       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).

DIAGNOSTICS    [Toc]    [Back]

     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 network,
 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
won't 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 this message appears at boot time and the driver fails to
attach the
     device  as a network interface, a second warm boot will have
to be performed
 to have the device properly configured.

     Note that this condition only occurs when warm booting  from
another operating
  system.  If the system is powered down prior to booting OpenBSD,
     the card should be configured correctly.
