the following optional parameters are used by entering them on the command line with the modprobe or insmod command using this syntax:

    modprobe e1000 [[option]=[val1],[val2],...]

    insmod e1000 [[option]=[val1],[val2],...]

    for example, with two pro/1000 pci adapters, entering:

    insmod e1000 txdescriptors=80,128

    loads the e1000 driver with 80 tx resources for the first adapter and 128 tx resources for the second adapter.

    the default value for each parameter is generally the recommended setting, unless otherwise noted.

    for more information about the autoneg, duplex, and speed parameters, see the speed and duplex configuration section in this document.
