`devn-el900.so`

Driver for 3Com 90x Network Interface Cards

Syntax:

io-pkt-variant -d el900 [option[,option ...]] ... &

where variant is one of v4, v4-hc, or v6-hc.

Options:

Use commas, not spaces, to separate the options.

connector=0|1|2|3

Network cable connector type:

0: BNC
1: UTP
2: AUI
3: FIBER

The default is automatically detected on supported hardware.

did=0xXXXX

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.

lan=num

The LAN number. The default is 0.

mac=XXXXXXXXXXXX

MAC address of controller. The default is automatically detected on supported hardware.

mru=num

Maximum receive unit. The default is 1514.

mtu=num

Maximum transmission unit. The default (1514) is automatically detected on supported hardware.

nomulticast

Disables the driver from sending or receiving multicast packets. By default, multicast is enabled.

promiscuous

Enable promiscuous mode. The default is off.

receive=num

Set the number of receive descriptors. The default is 64.

transmit=num

Set 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

PCI vendor ID. The default is automatically detected on supported hardware.

Description:

The devn-el900.so driver controls 3Com 90x Network Interface Cards (NICs). The IRQ of the interface is automatically detected on supported hardware. This is a legacy io-net driver; its interface names are in the form enX, 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 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-v6-hc using the 90x NIC driver:

io-pkt-v6-hc -d el900 verbose
ifconfig en0 10.1.0.184
