41 .Nd ERI/GEM/GMAC Ethernet device driver
43 To compile this driver into the kernel,
44 place the following lines in your
45 kernel configuration file:
46 .Bd -ragged -offset indent
51 Alternatively, to load the driver as a
52 module at boot time, place the following line in
54 .Bd -literal -offset indent
60 driver provides support for the GMac Ethernet hardware found mostly in
61 the last Apple PowerBooks G3s and most G4-based Apple hardware, as
62 well as many Sun UltraSPARCs.
65 Chips supported by the
73 Sun ERI 10/100 Mbps Ethernet
75 Sun GEM Gigabit Ethernet
81 .Va local-mac-address?
82 system configuration variable which can be set in the Open Firmware boot
91 driver will use the system's default MAC address for all of its devices.
94 the unique MAC address of each interface is used if present rather than
95 the system's default MAC address.
97 Supported interfaces having their own MAC address include the on-board
98 Sun ERI 10/100 Mbps on boards equipped with more than one Ethernet interface
99 and the Sun Gigabit Ethernet 2.0/3.0 GBE add-on cards.
103 driver fails to attach to Sun Gigabit Ethernet 2.0/3.0 (GBE/P) cards,
104 as the SERDES used on these cards is not supported so far.
107 driver will also fail to probe and attach to Sun Gigabit Ethernet 2.0/3.0 (GBE/S) cards,
108 as no SBus front-end has been written so far.
