- Sun Cassini/Cassini+ and National Semiconductor DP83065 Saturn Gigabit Ethernet driver
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Cd device miibus

Alternatively, to load the driver as a
module at boot time, place the following line in
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.
All controllers supported by the
driver have TCP/UDP checksum offload capability for both receive and
transmit, support for the reception and transmission of extended frames
and an interrupt coalescing/moderation mechanism as well as a 512-bit
multicast hash filter.
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
utility configures the adapter to receive and transmit Jumbo Frames.
The chips supported by the
- National Semiconductor DP83065 Saturn Gigabit Ethernet
- Sun Cassini Gigabit Ethernet
- Sun Cassini+ Gigabit Ethernet
following add-on cards are known to work with the
driver at this time:
- Sun GigaSwift Ethernet 1.0 MMF (Cassini Kuheen)
(part no. 501-5524)
- Sun GigaSwift Ethernet 1.0 UTP (Cassini)
(part no. 501-5902)
- Sun GigaSwift Ethernet UTP (GCS)
(part no. 501-6719)
- Sun Quad GigaSwift Ethernet UTP (QGE)
(part no. 501-6522)
- Sun Quad GigaSwift Ethernet PCI-X (QGE-X)
(part no. 501-6738)
On sparc64 the

If set to
(the default), the
driver will use the systems default MAC address for all of its devices.
If set to
the unique MAC address of each interface is used if present rather than
the systems default MAC address.
Supported interfaces having their own MAC address include on-board
versions on boards equipped with more than one Ethernet interface and
all add-on cards.
