.Sh NAME
|
|
.Nm gem
|
|
.Nd ERI/GEM/GMAC Ethernet 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 gem"
|
|
.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_gem_load="YES"
|
|
.Ed

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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 Sun UltraSPARC machines.
|
|
.Pp
|
|
All controllers supported by the
|
|
.Nm
|
|
driver have TCP checksum offload capability for both receive and transmit,
