|
.Nm cas
|
|
.Nd Sun Cassini/Cassini+ and National Semiconductor DP83065 Saturn Gigabit Ethernet 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 cas"
|
|
.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_cas_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Sun Cassini/Cassini+ and National
|
|
Semiconductor DP83065 Saturn Gigabit Ethernet controllers found
|
|
on-board in Sun UltraSPARC machines and as add-on cards.
|
|
.Pp
|
|
All controllers supported by the
|
|
.Nm
|
|
driver have TCP/UDP checksum offload capability for both receive and
|
|
transmit, support for the reception and transmission of extended frames
|
|
for
|
|
.Xr vlan 4
|
|
and an interrupt coalescing/moderation mechanism as well as a 512-bit
|
|
multicast hash filter.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver also supports Jumbo Frames (up to 9022 bytes), which can be
|
|
configured via the interface MTU setting.
|
|
Selecting an MTU larger than 1500 bytes with the
|
|
.Xr ifconfig 8
|
|
utility configures the adapter to receive and transmit Jumbo Frames.
|
|
.Sh HARDWARE
|
|

|
|
.Nm
|

driver are:

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver appeared in
|
|
.Fx 8.0
|
|
and
|
|
.Fx 7.3 .
|
|
It is named after the
|
|
.Nm
|
|
driver which first appeared in
|
|
.Ox 4.1
|
|
and supports the same set of controllers but is otherwise unrelated.
|

.Nm
|
|
driver was written by

.An Marius Strobl Aq Mt marius@FreeBSD.org
|
|
based on the
|
|
.Xr gem 4
|
|
driver.
