NAME

hme - Sun Microelectronics STP2002-STQ Ethernet interfaces device driver

SYNOPSIS

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

device miibus device hme

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

if_hme_load="YES"

DESCRIPTION

The ifconfig driver supports Sun Microelectronics STP2002-STQ ``Happy Meal Ethernet'' Fast Ethernet interfaces.

All controllers supported by the ifconfig driver have TCP checksum offload capability for both receive and transmit, support for the reception and transmission of extended frames for vlan(4) and a 128-bit multicast hash filter.

HARDWARE

The ifconfig driver supports the on-board Ethernet interfaces of many Sun UltraSPARC workstation and server models.

Cards supported by the ifconfig driver include:

• Sun PCI SunSwift Adapter (``SUNW,hme'' )
• Sun SBus SunSwift Adapter ``( hme'' and ``SUNW,hme''
• Sun PCI Sun100BaseT Adapter 2.0 (``SUNW,hme'' )
• Sun SBus Sun100BaseT 2.0 (``SUNW,hme'' )
• Sun PCI Quad FastEthernet Controller (``SUNW,qfe'' )
• Sun SBus Quad FastEthernet Controller (``SUNW,qfe'' )

NOTES

On sparc64 the ifconfig driver respects the local-mac-address? system configuration variable which can be set in the Open Firmware boot monitor using the setenv command or by eeprom(8). If set to ``false '' (the default), the ifconfig driver will use the system's default MAC address for all of its devices. If set to ``true '' the unique MAC address of each interface is used if present rather than the system's default MAC address.

Supported interfaces having their own MAC address include on-board versions on boards equipped with more than one Ethernet interface and all add-on cards except the single-port SBus versions.
