HME(4)			     Kernel Interfaces Manual			  HME(4)

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 capa-
     bility for both receive and transmit, support for the reception and  trans-
     mission 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 configura-
     tion 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.
