NAME
     hme — Sun Microelectronics STP2002-STQ Ethernet interfaces device driver


SYNOPSIS
     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device miibus
           device hme

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           if_hme_load="YES"


DESCRIPTION
     The hme driver supports Sun Microelectronics STP2002-STQ “Happy Meal Ethernet” Fast Ethernet
     interfaces.

     All controllers supported by the hme driver have TCP checksum offload capability for both
     receive and transmit, support for the reception and transmission of extended frames for
     vlan(4) and a 128-bit multicast hash filter.


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”)


NOTES
     On sparc64 the hme driver respects the local-mac-address? system configuration variable
     which can be set in the Open Firmware boot monitor using the setenv command or by eeprom(8).
     If set to “false” (the default), the hme driver will use the system's default MAC address
     for all of its devices.  If set to “true”, the unique MAC address of each interface is used
     if present rather than the system's default MAC address.

     Supported interfaces having their own MAC address include on-board versions on boards
     equipped with more than one Ethernet interface and all add-on cards except the single-port
     SBus versions.

HISTORY
     The hme driver first appeared in NetBSD 1.5.  The first FreeBSD version to include it was
     FreeBSD 5.0.
