gem - ERI/GEM/GMAC Ethernet device driver
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The gem 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.
Chips supported by the gem driver include:
· Apple GMAC
· Sun ERI 10/100 Mbps Ethernet
· Sun GEM Gigabit Ethernet
On sparc64 the gem 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 gem 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
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.
Currently the gem driver fails to attach to Sun Gigabit Ethernet 2.0/3.0
(GBE/P) cards, as the SERDES used on these cards is not supported so far.
The gem driver will also fail to probe and attach to Sun Gigabit Ethernet
2.0/3.0 (GBE/S) cards, as no SBus front-end has been written so far.

The gem device driver appeared in NetBSD 1.6. The first FreeBSD version
to include it was FreeBSD 5.0.
The gem driver was written by Eduardo Horvath 〈eeh@NetBSD.org〉. The man
page was written by Thomas Klausner 〈wiz@NetBSD.org〉.
