IBM PCI Token-Ring network driver (QNX)
Net.solotr [-f tx_forget_time] [-i irq] [-l log_net_id]
[-n tx_num_retries] [-p pci_slot] [-r media_rate]
[-s speed] [-t tx_retry_ticks] [-v] &
- -f tx_forget_time
- After a driver-level NACK is received from a remote
node, Net.solotr 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 two seconds, after
which the eternally optimistic Net.solotr stops
throttling its output. The -f allows you to
change the default two-second interval.
- -i irq
- Program the card to use the specified hardware
interrupt. This option overrides the default autodetect. If
the autodetect doesn't work on an ISA card, you have a
hardware conflict.
- -l log_net_id
- (``el'') Connect to the specified logical
network. The default is 1.
- -n tx_num_retries
- After failing to transmit to a remote node, retry
transmission no more than this number of times. The default
is 7.
- -p pci_index
- Have the driver look at this specific PCI Index for a
solotr-compatible card. You should have to specify
-p only if you have more than one
solotr-compatible card installed (e.g. -p0, -p1, -p2).
- -r media_rate
- Advertise the specified bit-transmission rate. The
default is 100000000. This information is used by the
Network Manager when multiple network drivers are running.
- -s speed
- Set the speed at which the card should run (e.g.
-s4 or -s16). Only possible with
100Mbit cards. This disables the auto-negotiation capability
of the ethernet card.
- -t tx_retry_ticks
- The number of 50-millisecond intervals between
tx retries. The default is 6.
- -v
- Be verbose; print out hardware configuration info on the
screen when starting up.
The Net.solotr network driver has been tested
with IBM's PCI Token-Ring Adapter (P/N 41H8900). The driver
supports automatic ring-speed detection. Auto-negotiation
can be disabled by using the
-s speed command-line option.
Net.solotr provides the Network Manager with
reliable data transfer over a Token-Ring network.
Most of the time, you shouldn't need to specify the I/O port
or the hardware interrupt to Net.solotr -
it should autodetect these parameters from the PCI BIOS.
Before installing your card, you should read the technote
contained in the /etc/readme/technotes/Net.solotr.relnotes
file.
If you install more than one network card, you must specify
a unique network ID (-l option) to every network
driver. If more than one solotr-compatible PCI card is
installed, you'll need to use the -p option (e.g.
-p0 for the first card, -p1 for the
second, etc.
Start the Net.solotr driver with default
parameters:
Net.solotr &
Start the Net.solotr driver and force the speed
to 4Mbit:
Net.solotr -s4 &
Start two copies of the driver running on separate cards,
one on logical network 1, the other on logical network 2:
Net.solotr -p0 -l1 &
Net.solotr -p1 -l2 &
