Driver for 3Com 90x Network Interface Cards
Syntax:
io-pkt-variant -d el900 [option[,option ...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Options:
Note:
Use commas, not spaces, to separate the options.
- connector=0|1|2|3
- Network cable connector type:
- 0
- BNC
- 1
- UTP
- 2
- AUI
- 3
- FIBER
The default is automatically detected on supported hardware.
- did=0xXXXX
- PCI device ID. The default is
automatically detected on supported hardware.
- duplex=0|1
- Half (0) or full (1) duplex mode. The default is
automatically detected on supported hardware.
If you specify duplex, specify speed as well;
if duplex alone is specified, it is ignored and both speed and duplex
are auto-negotiated.
- lan=num
- The LAN number.
The default is 0.
- mac=XXXXXXXXXXXX
- MAC address of controller. The default is
automatically detected on supported hardware.
- mru=num
- Maximum receive unit. The default is 1514.
- mtu=num
- Maximum transmission unit. The default (1514) is
automatically detected on supported hardware.
- nomulticast
- Disables the driver from sending or receiving multicast packets.
By default, multicast is enabled.
- promiscuous
- Enable promiscuous mode. The default is off.
- receive=num
- Set the number of receive descriptors. The default is 64.
- transmit=num
- Set the number of transmit descriptors. The default is 128.
- verbose or
verbose=num
- Be verbose. Specify num for more verbosity (num can be 1-4, the higher
the number, the more detailed the output).
The output goes to slogger;
invoke sloginfo to view it.
- vid=0xXXXX
- PCI vendor ID. The default is
automatically detected on supported hardware.
Description:
The devn-el900.so driver controls 3Com 90x Network Interface
Cards (NICs). The IRQ of the interface is automatically detected on
supported hardware.
This is a legacy io-net driver;
its interface names are in the form enX, where
X is an integer.
Note:
If the device enumerators (see
enum-devices)
don't recognize your device, try explicitly specifying
the device ID with the
did option when you start the driver.
Some devices support hardware checksums, although some might do so in
only one direction; to determine if your device does, type:
ifconfig enX
and look for the following in the list of supported options:
- ip4csum, ip4csum-rx, ip4csum-tx
- tcp4csum, tcp4csum-rx, tcp4csum-tx
- tcp6csum, tcp6csum-rx, tcp6csum-tx
- udp4csum, udp4csum-rx, udp4csum-tx
- udp6csum, udp6csum-rx, udp6csum-tx
You can then use
ifconfig
to enable or disable whichever of these options your device supports.
Examples:
Start io-pkt-v6-hc using the 90x NIC driver:
io-pkt-v6-hc -d el900 verbose
ifconfig en0 10.1.0.184
Files:
- /dev/io-net
- The directory where, by default, drivers and protocol modules add
entries.
