NAME    [Toc]    [Back]

     hme - Sun Happy Meal Ethernet

SYNOPSIS    [Toc]    [Back]

     hme* at pci? dev ? function ?
     hme* at sbus? slot ? offset ?
     nsphy* at mii? phy ?
     qsphy* at mii? phy ?

DESCRIPTION    [Toc]    [Back]

     The hme interface provides access to the 10Mb/s and  100Mb/s
Ethernet networks
 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

     Each of the host's network addresses is  specified  at  boot
time with an
     SIOCSIFADDR ioctl(2).  The hme interface employs the address
     protocol described in arp(4) to dynamically map between  Internet and Ethernet
 addresses on the local network.

     When  a hme interface is brought up, by default, it will attempt to autonegotiate
 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
     ifconfig(8) command.  The supported media types are:

           media autoselect  Attempt to autoselect the media type

           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    [Toc]    [Back]

     OpenBSD support for the hme first appeared in OpenBSD 2.4.

CAVEATS    [Toc]    [Back]

     The  hme  sbus  cards will not function in a sun4c class machine, due to
     PROM limitations.
