devnp-speedo.so

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.

Runs on:

Neutrino

Options:

---

Use commas, not spaces, to separate the options.

---

did=0xXXXX

Device ID. Only attach to device 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.

---

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.

promiscuous

Enable promiscuous mode. The default is off.

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
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.

---

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 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.

Examples:

Start io-pkt using the devnp-speedo.so driver and the full TCP/IP stack:

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 and the full TCP/IP stack. 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
