|
Use commas, not spaces, to separate the options. |
- did=0xXXXX
- Detect only devices with this specific 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.
You can also use ifconfig -m and
ifconfig wmX media to set this.
- irq=N
- IRQ of the interface. The default is automatically detected on supported
hardware.
- mac=XXXXXXXXXXXX
- The MAC address of the controller.
The default is automatically detected on supported hardware.
- mtu=N
- The maximum transmission unit.
The default is 1514.
- 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 only devices at this specific PCI index.
- priority=N
- The priority of the driver's event-handler thread (default 21).
- promiscuous
- Enable reception of all packets.
- receive=num
- The number of receive descriptors; the default is 64.
- speed=N
- Force the link speed (specified in Mbits/second).
If you specify speed, specify duplex as well;
if speed alone is specified, the specified speed is correctly set,
but duplex defaults to half (0).
You can also use ifconfig -m and
ifconfig wmX media to set this.
- transmit=N
- The number of transmit descriptors; the default is 128.
- verbose
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.
The devnp-e1000.so driver manages all current Intel Gigabit devices.
This is a native io-pkt driver;
its interface names are in the form wmX, where
X is an integer.
The devnp-e1000.so and
devnp-i82544.so
drivers are similar:
- devnp-i82544.so has performance
optimizations (TSO and interrupt thresholding options) that
may make it a better performing candidate for some hardware
- devnp-e1000.so likely supports more hardware
|
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 wmX
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.
Start io-pkt using the devnp-e1000.so driver
and the full TCP/IP stack:
io-pkt -d e1000
ifconfig wm0 192.168.0.10
devn-*,
devnp-*,
ifconfig,
io-pkt
