Net.ether9000

SMC91C90/91C92 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.
-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.
-p io_port: Use the specifed I/O port base. 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.
-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.
-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 10baseT. If a is specified, the connection type is AUI/coax.
-v: Be verbose; print out hardware configuration info on the screen when starting up.

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  &

Description:

The Net.ether9000 network driver communicates directly with a SMC91C90 or SMC91C92 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).

Exit status:

Net.ether9000 terminates only upon encountering errors during initialization or opon 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.

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.
