# 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.
