To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device miibusdevice gem
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_gem_load="YES"
DESCRIPTION
The
driver provides support for the GMac Ethernet hardware found mostly in
the last Apple PowerBooks G3s and most G4-based Apple hardware, as
well as many Sun UltraSPARCs.
HARDWARE
Chips supported by the
driver include:
Apple GMAC
Sun ERI 10/100 Mbps Ethernet
Sun GEM Gigabit Ethernet
The
following add-on cards are known to work with the
driver at this time:
Sun Gigabit Ethernet PCI 2.0/3.0 (GBE/P)
(part no. 501-4373)
NOTES
On sparc64 the
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
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 the on-board
Sun ERI 10/100 Mbps on boards equipped with more than one Ethernet interface
and the Sun Gigabit Ethernet 2.0/3.0 GBE add-on cards.
CAVEATS
Currently the
driver fails to attach to Sun Gigabit Ethernet SBus 2.0/3.0 (GBE/S) cards,
as no SBus front-end has been written so far.
