DESCRIPTION
The hme interface provides access to the 10Mb/s and 100Mb/s Ethernet net-
works via the National DP83840 Ethernet 10/100 Mb/s Physical Layer or the
Quality QS6612 Ethernet MII Transceiver for Category 5 Twisted Pair Cable
chip sets. The hme is found on the SunSwift and Sun QuadFastEthernet
boards.
Each of the host's network addresses is specified at boot time with an
SIOCSIFADDR ioctl(2). The hme interface employs the address resolution
protocol described in arp(4) to dynamically map between Internet and Eth-
ernet addresses on the local network.
When a hme interface is brought up, by default, it will attempt to auto-
negotiate the link speed and duplex. The speeds, in order of attempt,
are: 100 Mb/s Full Duplex, 100 Mb/s Half Duplex, 10 Mb/s Full Duplex, and
10 Mb/s Half Duplex.
The hme supports several media types, which are selected via the
ifconfig(8) command. The supported media types are:
media autoselect Attempt to autoselect the media type (default)
media 100baseTX mediaopt full-duplex
Use 100baseTX, full duplex
media 100baseTX mediaopt half-duplex
Use 100baseTX, half duplex
media 10baseT mediaopt full-duplex
Use 10baseT, full duplex
media 10baseT mediaopt half-duplex
Use 10baseT, half duplex

HISTORY
OpenBSD support for the hme first appeared in OpenBSD 2.4.
CAVEATS
The hme sbus cards will not function in a sun4c class machine, due to
PROM limitations.
