40.3. Specifying Module Parameters
In some situations, it may be necessary to supply parameters to
a module as it is loaded for it to function properly.
For instance, to enable full duplex at 100Mbps connection speed
for an Intel Ether Express/100 card, load the e100 driver with the
e100_speed_duplex=4 option.
Caution
When a parameter has commas, be sure not
to put a space after a comma.
Tip
The modinfo command is also
useful for listing various information about a kernel module,
such as version, dependencies, paramater options, and aliases.
