NAME
se - SiS 190/191 10/100/Gigabit Ethernet device

SYNOPSIS
se* at pci?
atphy* at mii?
brgphy* at mii?
eephy* at mii?
etphy* at mii?
rlphy* at mii?

DESCRIPTION
The se driver provides support for the SiS190 Fast Ethernet controller integrated into the SiS965L and SiS966L southbridges, and the SiS191 Gigabit controller integrated into the SiS965 and SiS966 southbridges.

Both SiS 190 and SiS 191 embed an Ethernet MAC with external PHY. They use a bus master DMA and a scatter/gather descriptor scheme and include a 64-bit multicast hash filter.

The se 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 the hostname.if(5) file.

10baseT
    Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX
    Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

1000baseSX
    Set 1000Mbps (Gigabit Ethernet) on fiber operation. Only full-duplex mode is supported at this speed.

1000baseT
    Set 1000Mbps (Gigabit Ethernet) on copper operation.

The se 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).

DIAGNOSTICS

se0: EEPROM read timeout The driver could not read the controller's MAC address from its EEPROM.

se0: invalid EEPROM signature The driver could not find the expected EEPROM signature and could not read the controller's MAC address.

se0: Could not find PCI-ISA bridge The driver could not read the controller's MAC address from the CMOS memory connected to the PCI-ISA bridge.

se0: PHY read timeout The driver could not read data from the PHY.

se0: PHY write timeout The driver could not write data to the PHY.

se0: watchdog timeout The device has stopped responding to the network, or there is a problem with the network connection (cable).
