The AMD chips provide a mechanism for zero-copy +receive, providing good performance in server environments. Receive +address filtering is provided using a single perfect filter entry +for the station address and a 64-bit multicast hash table. +.Pp +The +.Nm +driver supports the following media types: +.Pp +.Bl -tag -width 10baseTXUTP +.It autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode by adding media options to +.Xr rc.conf 5 . +.It 10baseT/UTP +Set 10Mbps operation. +The +.Xr ifconfig 8 +.Cm mediaopt +option can also be used to select either +.Sq full-duplex +or +.Sq half-duplex +modes. +.It 100baseTX +Set 100Mbps (fast ethernet) operation. +The +.Xr ifconfig 8 +.Cm mediaopt +option can also be used to select either +.Sq full-duplex +or +.Sq half-duplex +modes. +.El +.Pp +The +.Nm +driver supports the following media options: +.Pp +.Bl -tag -width full-duplex +.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 "pcn%d: couldn't map ports/memory" +A fatal initialization error has occurred. +.It "pcn%d: couldn't map interrupt" +A fatal initialization error has occurred. +.It "pcn%d: watchdog timeout" +The device has stopped responding to the network, or there is a problem with +the network connection (e.g. a cable fault). +.It "pcn%d: no memory for rx list" +The driver failed to allocate an mbuf for the receiver ring. +.It "pcn%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 clusisr. +.It "pcn%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 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 network interface, you will have to perform a +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. +.El +.Sh SEE ALSO +.Xr arp 4 , +.Xr netintro 4 , +.Xr ng_ether 4 , +.Xr ifconfig 8 +.Rs +.%T AMD PCnet/FAST, PCnet/FAST+ and PCnet/Home datasheets +.%O http://www.amd.com +.Re +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 5.0 . +.Sh AUTHORS +The +.Nm +driver was written by +.An Bill Paul Aq wpaul@osd.bsdi.com . |
