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 64 on PPC, and 128 on other platforms.
- 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 64 on PPC, and 512 on other platforms.
- 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.
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-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.
