.Sh NAME
.Nm hme
.Nd "Sun Microelectronics STP2002-STQ Ethernet interfaces device driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device miibus"
.Cd "device hme"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_hme_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports Sun Microelectronics STP2002-STQ
.Dq Happy Meal Ethernet
Fast Ethernet interfaces.
.Pp
All controllers supported by the
.Nm
driver have TCP checksum offload capability for both receive and transmit,
support for the reception and transmission of extended frames for
.Xr vlan 4
and a 128-bit multicast hash filter.
.Sh HARDWARE
The
.Nm
driver supports the on-board Ethernet interfaces of many
Sun
.Tn UltraSPARC
workstation and server models.
.Pp
Cards supported by the
.Nm
driver include:
.Pp
.Bl -bullet -compact
.It
Sun PCI SunSwift Adapter
.Pq Dq SUNW,hme
.It
Sun SBus SunSwift Adapter
.Dq ( hme
and
.Dq SUNW,hme )
.It
Sun PCI Sun100BaseT Adapter 2.0
.Pq Dq SUNW,hme
.It
Sun SBus Sun100BaseT 2.0
.Pq Dq SUNW,hme
.It
Sun PCI Quad FastEthernet Controller
.Pq Dq SUNW,qfe
.It
Sun SBus Quad FastEthernet Controller
.Pq Dq SUNW,qfe
.El
.Sh NOTES
On sparc64 the
.Nm
driver respects the
.Va local-mac-address?
system configuration variable which can be set in the Open Firmware boot
monitor using the
.Ic setenv
command or by
.Xr eeprom 8 .
If set to
.Dq Li false
(the default), the
.Nm
driver will use the system's default MAC address for all of its devices.
If set to
.Dq Li true ,
the unique MAC address of each interface is used if present rather than
the system's default MAC address.
.Pp
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.
