4-4 Command Line Parameters
If the driver is built as a module, the following optional parameters are used by enter-
ing them on the command line with the modprobe command using this syntax:
modprobe e1000 [<option>=<VAL1>,<VAL2>,...]
For example, with two PRO/1000 PCI adapters, entering:
modprobe e1000 TxDescriptors=80,128
loads the e1000 driver with 80 TX descriptors for the fi rst adapter and 128 TX
descriptors for the second adapter.
The default value for each parameter is generally the recommended setting, unless
otherwise noted.
NOTES:
For more information about the AutoNeg, Duplex, and Speed parameters, see the
Speed and Duplex Confi guration section in this document.
For more information about the InterruptThrottleRate, RxIntDelay, TxIntDelay, RxAb-
sIntDelay, and TxAbsIntDelay parameters, see the application note at: http://www.

A descriptor describes a data buffer and attributes related to the data buffer. This
information is accessed by the hardware.
