NAME
     hme - Sun Happy Meal 10/100 Ethernet device

SYNOPSIS
     hme* at pci?
     hme* at sbus?
     luphy* at mii?
     nsphy* at mii?
     qsphy* at mii?

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.

     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   Use 100baseTX, half duplex

           media 10baseT mediaopt full-duplex
                             Use 10baseT, full duplex

           media 10baseT     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.
