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.
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.
