-ADMtek Inc. AL981 Comet and AN985 Centaur fast ethernet device driver
-.Sh SYNOPSIS
-.Cd "device al0"
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for PCI ethernet adapters and embedded
-controllers based on the ADMtek Inc. AL981 Comet and AN 985
-Centaur fast ethernet controller chips.
-.Pp
-The ADMtek chip uses bus master DMA and is designed to be a
-DEC 21x4x workalike. The only major difference between the DEC
-and ADMtek parts is that the ADMtek receiver filter is programmed
-using two special registers where as the DEC chip is programmed
-by uploading a special setup frame via the transmit DMA engine.
-The AL981 and AN985 can only be programmed with a single
-perfect filter entry for the local station address and a 64-bit
-multicast hash table; the DEC filter supports several other
-options. The ADMtek fast ethernet controllers support both
-10 and 100Mbps speeds in either full or half duplex using
-an internal 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
-.Pp
-For more information on configuring this device, see
-.Xr ifconfig 8 .
-.Sh DIAGNOSTICS
-.Bl -diag
-.It "ax%d: couldn't map memory"
-A fatal initialization error has occurred.
-.It "ax%d: couldn't map interrupt"
-A fatal initialization error has occurred.
-.It "ax%d: watchdog timeout"
-The device has stopped responding to the network, or there is a problem with
-the network connection (cable).
-.It "ax%d: no memory for rx list"
-The driver failed to allocate an mbuf for the receiver ring.
-.It "ax%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 "ax%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.
