UNIX Driver Software: Broadcom NetXtreme 57XX User Guide
This section contains procedures for installing Broadcom NetXtreme Gigabit
Ethernet Adapter drivers for SCO OpenServer 5.0.7 and UnixWare 7 and includes
the following information:
SCO Open Server
UnixWare/OpenUnix 8
SCO OpenServer 5.0.7
Overview
This procedure describes the installation of the SCO OpenServer driver. This
driver is released as a media image file containing the driver package. The
media image file can be copied to the target machine directly for installation,
or from an installation diskette that you can create.
Creating a Diskette
- Copy the file VOL.000.000 to an SCO system.
- Create a diskette using: dd if=VOL.000.000 of=/dev/rfd0135ds18.
Installing the Driver
- Use custom or scoadmin software to install the SCO OpenServer driver from
the media image or from the floppy created above.
- After the package is installed, use netconfig to add the new network adapter.
- After added, modify the hardware configuration in Advanced Options to change
the Line Speed and Flow Control if desired. The settings for these properties
are listed below:
Line Speed
- AutoNegotiate (default) (all speeds advertised)
- Fixed HalfDuplex10
- Auto HalfDuplex10 (only 10 Mbps half-duplex advertised)
- Fixed FullDuplex10
- Auto FullDuplex10 (only 10 Mbps full-duplex advertised)
- Fixed HalfDuplex100
- Auto HalfDuplex100 (only 100 Mbps half-duplex advertised)
- Fixed FullDuplex100
- Auto FullDuplex100 (only 100 Mbps full-duplex advertised)
- Auto HalfDuplex1000 (only 1000 Mbps half-duplex advertised)
- Fixed FullDuplex1000 (NOTE 1)
- Auto FullDuplex1000 (only 1000 Mbps full-duplex advertised)
 |
NOTE 1: 1000 Mbps (1 Gbps) full-duplex fixed speed is only valid for
fiber connections. For copper, twisted-pair connections, 1 Gbps can only
be set through auto-negotiation with a 1 Gbps partner. |
Flow Control
- Off
- AutoNegotiate (Symmetric Pause advertised) (NOTE 2) (default)
- RxPause
- TxPause
- RxPause/TxPause
 |
NOTE 2: Auto-negotiation of Flow Control is only valid when
the Line Speed is set to AutoNegotiate (all speeds advertised or single
speed advertised). |
 |
NOTE 3: A kernel relink and reboot is required
before the new configuration will take effect. |
Jumbo Frames and Other Advanced Properties
Jumbo MTU sizes and other advanced, tunable properties for the BCM5700 controller
are located in the file space.c in the directory /etc/conf/pack.d/bcme. A description
for each parameter is contained in space.c. Modify the desired parameter in
space.c, rebuild the kernel by doing /etc/conf/bin/idbuild and rebooting the
system. Note that the MTU sizes can be individually set for each adapter in
the system, whereas all other properties apply globally to all adapters.
 |
NOTE: The BCM5705 does not support jumbo frames. It can transmit jumbo packets
by TCP segmentation, but the ethernet frame size is still limited to 1514
bytes. Receive frame size is also limited to 1514 bytes. |

UnixWare/OpenUnix 8
Overview
This procedure describes the installation procedure for the UnixWare driver.
The driver is released as an installable package in datastream format.
Installing the Driver
- Do the following to install the bcme package on the Unixware system:
pkgadd -d <install-path>.
Where <install-path> is the full path name of the installable package
bcme-<version>.pkg.
- After the package is installed, use netcfg or scoadmin network to add the
new network adapter.
- When prompted, select the Line Speed and then select Advanced Option for
Flow Control, MAC Address , and Jumbo MTU Size settings, if desired. The settings
for these properties are listed below:
Line Speed
- Auto-Negotiate (default) (all speeds advertised)
- 10 Mbps Half-Duplex Fixed
- 10 Mbps Half-Duplex Auto (only 10 Mbps half-duplex advertised)
- 10 Mbps Full-Duplex Fixed
- 10 Mbps Full-Duplex Auto (only 10 Mbps full-duplex advertised)
- 100 Mbps Half-Duplex Fixed
- 100 Mbps Half-Duplex Auto (only 100 Mbps half-duplex advertised)
- 100 Mbps Full-Duplex Fixed
- 100 Mbps Full-Duplex Auto (only 100 Mbps full-duplex advertised)
- 1000 Mbps Half-Duplex Auto (only 1000 Mbps half-duplex advertised)
- 1000 Mbps Full-Duplex Fixed (NOTE 1)
- 1000 Mbps Full-Duplex Auto (only 1000 Mbps full-duplex advertised)
 |
NOTE 1: 1000 Mbps (1 Gbps) full-duplex, fixed speed is only
valid for fiber connections. For copper, twisted-pair connections, 1 Gbps
can only be set through auto-negotiation with a 1 Gbps link partner. |
Flow Control
- Disabled
- Auto Negotiation (Symmetric Pause advertised) (NOTE 2) (default)
- Receive Pause
- Transmit Pause
- Receive & Transmit Pause
 |
NOTE 2: Auto-negotiation of Flow Control is only
valid when the Line Speed is set to Auto Negotiation (all speeds advertised
or single speed advertised). |
MAC Address
- No Override (default) - a user-administered MAC address entered with a colon
separating each hexadecimal byte (e.g., 12:34:56:78:9a:bc).
Jumbo MTU Size
- 1500 - 9000 (default is 1500)
Ethernet@Wirespeed
- Enabled (NOTE 3)
- Disabled (default)
 |
NOTE 3: Ethernet@Wirespeed allows the hardware to attempt to work with
broken ethernet cables. It is not recommended that this option be used
when configuring interfaces in team.
