Driver for Intel 82557, 82558, and 82559 Fast Ethernet LAN adapters
Syntax:
io-pkt-variant -d speedo [[index:option[,[index:option ...]] ... &
where variant is one of v4, v4-hc, or
v6-hc.
Options:
Note:
Use commas, not spaces, to separate the options.
- did=0xXXXX
- Device ID. Attach only to devices with this PCI index.
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, you must also specify speed.
- irq=num
- The IRQ of the interface.
The default is automatically detected on supported hardware.
- kermask=0|1
- Specify the masking:
- 1 — use the kernel interrupt-masking methodology.
- 0 — manually mask the NIC in the interrupt handler.
- mac=XXXXXXXXXXXX
- The MAC address of the controller.
The default is automatically detected on supported hardware.
- mmap
- Use memory-mapped registers. The default is I/O mapped.
Note:
The mmap option is supported on all targets except x86.
- nomulticast
- Disable the driver from sending or receiving multicast packets.
By default, multicast is enabled.
- pci=0xXXXX
- The PCI index of the controller.
The default is automatically detected on supported hardware.
- phy=num
- The address of the connected PHY device.
- receive=num
- The number of receive descriptors; the default is 256.
- speed=10|100
- The media data rate (10 Mbit or 100 Mbit operation).
The default (0) is automatically detected on supported hardware.
If you specify speed, you must also specify duplex.
- transmit=num
- The number of transmit descriptors; the default is 1024.
- 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
- Attach only to devices with this PCI vendor ID.
The default is 0x8086.
Description:
The devnp-speedo.so driver manages the Intel 82557, 82558, and 82559 Fast Ethernet LAN adapters.
This is a native io-pkt driver;
its interface names are in the form fxpX, 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 fxpX
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.
Note:
Native
io-pkt and ported NetBSD drivers don't put entries
into the
/dev/io-net namespace, so a
waitfor
command for such an entry won't work properly in buildfiles or scripts.
Use
if_up -p
instead; for example, instead of
waitfor /dev/io-net/fxp0, use
if_up -p fxp0.
Examples:
Start io-pkt using the devnp-speedo.so driver:
io-pkt -d speedo -p tcpip
ifconfig fxp0 10.1.0.184
For the second instance of the device in the system,
start io-pkt using the devnp-speedo.so driver,
but use increased verbosity and override the default MAC address:
io-pkt -d speedo verbose,idx1:mac=00:03:02:01:00:00 -p tcpip
ifconfig fxp0 10.1.0.184
