    NAME

    
    
    sis
    
     - SiS 900, SiS 7016 and NS DP83815/DP83816 Fast Ethernet device driver
    
     
    

    SYNOPSIS

    To compile this driver into the kernel, place the following lines in your kernel configuration file:
    device miibus device sis

    Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

    if_sis_load="YES"
    
     

    DESCRIPTION

    The driver provides support for PCI Ethernet adapters and embedded controllers based on the Silicon Integrated Systems SiS 900 and SiS 7016 Fast Ethernet controller chips.

    This driver also supports adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816 PCI Ethernet controller chip.

    The SiS 900 is a 100Mbps Ethernet MAC and MII-compliant transceiver in a single package. It uses a bus master DMA and a scatter/gather descriptor scheme. The SiS 7016 is similar to the SiS 900 except that it has no internal PHY, requiring instead an external transceiver to be attached to its MII interface. The SiS 900 and SiS 7016 both have a 128-bit multicast hash filter and a single perfect filter entry for the station address.

    The NS DP83815 is also a 100Mbps Ethernet MAC with integrated PHY. The NatSemi chip and the SiS 900 share many of the same features and a fairly similar programming interface, hence both chips are supported by the same driver.

    The 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 rc.conf5.
    10baseT/UTP
    Set 10Mbps operation. The ifconfig(8) mediaopt option can also be used to select either `full-duplex' or `half-duplex' modes.
    100baseTX
    Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either `full-duplex' or `half-duplex' modes.

    The 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).  

    HARDWARE

    The driver supports Silicon Integrated Systems SiS 900 and SiS 7016 based Fast Ethernet adapters and embedded controllers, as well as Fast Ethernet adapters based on the National Semiconductor DP83815 (MacPhyter) and DP83816 chips. Supported adapters include:

     

    DIAGNOSTICS

    "sis%d: couldn't map ports/memory"
    A fatal initialization error has occurred.
    "sis%d: couldn't map interrupt"
    A fatal initialization error has occurred.
    "sis%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).
    "sis%d: no memory for rx list"
    The driver failed to allocate an mbuf for the receiver ring.
    "sis%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.
    "sis%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.

    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.
