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.
When a parameter has commas, be sure not to put a space after a comma.
The modinfo command is also useful for listing various information about a kernel module, such as version, dependencies, paramater options, and aliases.
