Net.ether9000

SMC91C90/91C92/91C100FD Ethernet network driver (QNX)

Syntax:

Net.ether9000 [options] &

Options:

-c

Program the NIC to monitor the carrier when transmitting.

-f tx_forget_time

After a driver-level NACK is received from a remote node, Net.ether9000 will assume that because packets were dropped, throttling the transmit output on that connection would be a good idea. So, the output will be reduced to approximately 400K/sec for 10 seconds, after which the eternally optimistic Net.ether9000 stops throttling its output. The -f option allows you to change the default 10 seconds above.

-F

Enable full-duplex operation.

-h hang_ticks

Specify the number of 50ms ticks to wait until the driver concludes that the chip is hung and resets it. Default: 10 (500ms).

-i irq

Specify hardware interrupt (default is to autodetect)

-l log_net_id

("el") Connect to the specified logical network. The default is 1.

-M

Program the NIC for multicast receive mode. All packets with multicast destination addresses will be buffered.

-n tx_num_retries

After failing to transmit to a remote node, retry transmission no more than this number of times. Default is 3.

-o

Use fiber optic links.

-p io_port

Use the given I/O port base, specified as a hexadecimal number without a leading 0x. This option overrides the autodetect.

-P

Program the NIC for promiscuous receive mode. All packets will be buffered, regardless of the packet's destination address. The default is non-promiscuous mode.

You may use this option in conjunction with netsniff to monitor other traffic on the network.

-r media_rate

Advertise the specified bit-transmission rate. The default is 10000000. This information is used by the Network Manager when multiple network drivers are running.

-s speed

Specify the data rate, e.g. -s10 or -s100. Default is auto-negotiate. Use of this option disables the auto-negotiation capability of the ethernet card.

-t tx_retry_ticks

The number of 50 millisecond intervals between transmit retries. The default is 20.

-T [a|t]

Specify connection type. If t is specified, the connection type is 10BASE-T. If a is specified, the connection type is AUI/coax.

-v

Be verbose; print out hardware configuration info on the screen when starting up.

Description:

The Net.ether9000 network driver communicates directly with a SMC91C90, SMC91C92, or SMC91C100FD compatible Ethernet network card. It provides the Network Manager with reliable data transfer over an Ethernet network.

Before installing your card, you should read the technote contained in the /etc/readme/technotes/Net.ether9000 file.

If you install more than one network card, you must specify a unique network ID (-l option) to every network driver. If you install more than one SMC9000 or compatible network card, you must also specify the -p options for every invocation of Net.ether9000 (except the one with the lowest I/O port).

Examples:

On an SMC91C92, scan for card and autodetect IRQ:

    Net.ether9000  &

On an SMC91C92, use I/O port 340h and autodetect IRQ:

      Net.ether9000 -p 340 &

One card is using I/O port 300h (scan will detect first) on logical network 1. The second card is using I/O port 320h on logical network 2:

      Net.ether9000 &
      Net.ether9000 -p 320 -l 2  &

Files:

Net.ether9000 closes its standard input, standard output and standard error immediately after initialization.

Error messages are displayed via the qnx_display_*() functions, not through standard error.

Signals:

The Net.ether9000 driver ignores SIGPWR.

Exit status:

Net.ether9000 terminates only upon encountering errors during initialization or upon getting a signal (i.e. being killed).

0

Net.ether9000 has shut down successfully and cleanly deregistered from Net.

>0

An error occurred during initialization.
