NAME

hme — Sun Microelectronics STP2002-STQ Ethernet interfaces device driver

SYNOPSIS

hme* at pci? dev ? function ?
hme* at sbus? slot ? offset ?

DESCRIPTION

The hme driver supports Sun Microelectronics STP2002-STQ Fast Ethernet interfaces.

HARDWARE

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

Cards supported by the hme 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”)

The STP2002 family supports hardware checksumming to assist in computing IPv4 TCP/UDP checksums. The hme driver supports this feature of the chip. See ifconfig(8) for information on how to enable this feature.

HISTORY

The hme driver first appeared in NetBSD 1.5.

AUTHORS

The hme driver was written by Paul Kranenburg <pk@NetBSD.org>.

BUGS

Connecting a MII transceiver on those cards that support it will cause the RJ45 connector to be detected as PHY instance 1, instead of the default instance 0.
