This commit adds device driver support for the Sundance Technologies ST201

PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)

This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.

The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.

+Sundance Technologies ST201 fast ethernet device driver
+.Sh SYNOPSIS
+.Cd "controller miibus0"
+.Cd "device ste0"
+.Sh DESCRIPTION
+The
+.Nm
+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.
+.Pp
+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.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It autoselect
+Enable autoselection of the media type and options.
+The user can manually override
+the autoselected mode by adding media options to the
+.Pa /etc/rc.conf
+fine.
+.It 10baseT/UTP
+Set 10Mbps operation. The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex modes.
+.It 100baseTX
+Set 100Mbps (fast ethernet) operation. The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex
+modes.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It full-duplex
+Force full duplex operation
+.It half-duplex
+Force half duplex operation.
+.El

+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "ste%d: couldn't map ports/memory"
+A fatal initialization error has occurred.
+.It "ste%d: couldn't map interrupt"
+A fatal initialization error has occurred.
+.It "ste%d: watchdog timeout"
+The device has stopped responding to the network, or there is a problem with
+the network connection (cable).
+.It "ste%d: no memory for rx list"
+The driver failed to allocate an mbuf for the receiver ring.
+.It "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.
+.It "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
+you see this message at boot time and the driver fails to attach
+the device as a network interface, you will have to perform second
+warm boot to have the device properly configured.
+.Pp
+Note that this condition only occurs when warm booting from another
+operating system. If you power down your system prior to booting
+.Fx ,
+the card should be configured correctly.
