Adapter Driver Parameters
Parameter Meaning
tx_flow_control
If link negotiation is on, a value of 1 allows the
adapter to negotiate 802.3x transmit flow control
with the device at the other end of the link. If
802.3x flow control is supported by the other
device, transmit pause packets will be respected. A
value of 0 disables transmit flow control. The
default is 0 (off).
hybrid_len (Do not use; value is set by startup file)
shared_rupt (Do not use; value is set by startup file)

Used to set the device number from which the
previous data is extracted. This value can range
from 0 to the number of adapters installed in the
system. The default is 0.

Checking Parameter Settings
To check a current parameter setting, use the following command:
# ndd /dev/alt <parameter_name>
Setting Parameters
Follow this procedure to set parameters using the ndd utility:
1. Check the /etc/path_to_inst file for the instance
associated with particular devices.
2. Specify the instance for the adapter you wish to configure:
# ndd -set /dev/alt instance <instance#>
Any subsequent ndd configuration commands will act on the
adapter with the selected instance. The adapter remains selected
until you specify a different instance.
3. Specify the configuration command using the following format:
# ndd -set /dev/alt <parameter> <value>
