+ASIX Electronics AX88140A and AX88141 Fast Ethernet device driver
+.Sh SYNOPSIS
+.Cd "ax* at pci? dev ? function ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for PCI Ethernet adapters and embedded
+controllers based on the ASIX AX88140A and AX88141 Fast Ethernet
+controller chips, including the Alfa Inc. GFC2204 and the CNet Pro110.
+The AX88141 is a new version of the AX88140A with power management
+and magic packet support.
+.Pp
+The ASIX chip uses bus master DMA and is designed to be a
+DEC 21x4x workalike. The only major difference between the DEC
+and ASIX parts is that the ASIX 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 ASIX receive filter 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 ASIX Fast Ethernet controller supports both
+10 and 100Mbps speeds in either full or half duplex using
+an external 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
+file.
+.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

+.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.
