Driver for Intel Gigabit Ethernet LAN adapters and I/O Controller Hubs
Syntax:
io-pkt-variant -d /lib/dll/devn-i82544.so
[option[,option ...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Note:
If you don't specify the full path to
devn-i82544.so,
io=pkt* starts
devnp-i82544.so.
Options:
Note:
Use commas, not spaces, to separate the options.
- did=0xXXXX
- Detect only devices with the given 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 you specify duplex alone, it's ignored, and both speed and duplex are auto-negotiated.
- flowcontrol=0|1
- Disable (0) or enable (1) hardware flow control.
- irq=N
- IRQ of the interface. The default is automatically detected on supported hardware.
- lan=num
- The LAN number. The default is 0.
- mac=XXXXXXXXXXXX
- MAC address of controller. The default is automatically detected on supported hardware.
- mtu=X
- Maximum transmission unit. The default (1514) is automatically detected on supported hardware.
- nomulticast
- Disable the driver from sending or receiving multicast packets. By default, multicast is enabled.
- pauseignore
- Ignore pause frames with respect to full duplex flow control.
- pausesuppress
- Suppress pause frames with respect to full duplex flow control.
- pci=0xXXXX
- Detect devices only at this specific PCI index.
- priority=X
- Priority of the driver's event-handler thread. The default is 21.
- promiscuous
- Enable promiscuous mode. The default is off.
- receive=num
- Set the number of receive descriptors.
The default is 128.
- speed=10|100|1000
- Media data rate (10Mbit, 100Mbit, or Gigabit operation).
The default is automatically detected on supported hardware.
If you specify speed, specify duplex as well;
if you specify speed alone, the specified speed is correctly set,
but duplex defaults to half (0).
- transmit=num
- Set the number of transmit descriptors.
The default is 512.
- 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
- Detect only devices with this specific PCI vendor ID.
Description:
The devn-i82544.so driver manages the Intel
82540, 82541, 82542, 82543, 82544, 82545, 82546, 82547, 82571, 82572, and
82573 Gigabit Ethernet LAN adapters,
and the ICH8 and ICH9 I/O Controller Hubs.
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-v4-hc using the devn-i82544.so driver:
io-pkt-v4-hc -d /lib/dll/devn-i82544.so
ifconfig en0 10.1.0.184
Files:
- /dev/io-net
- The directory where, by default, drivers and protocol modules add entries.
