NAME

     EBus -- introduction to SPARC EBus bus support and drivers

SYNOPSIS

     ebus* at pci?

DESCRIPTION

     The EBus bus is designed to provide the ability to put ISA and traditional Intel-style peripherals in a SPARC based system with a minimal
     amount of glue logic.  Typically, it is implemented in the PCIO IC from SME, which also implements a hme(4) compatible PCI network device
     ('network').  The EBus has four DMA channels, similar to the DMA seen in the esp(4) SCSI DMA.

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.
