* This code is used to simulate a PCI probe by parsing information in
* sysfs. Moreover, when a registered driver matches a device, the
* kernel driver currently using it is unloaded and replaced by
- * igb_uio module, which is a very minimal userland driver for Intel
+ * nic_uio module, which is a very minimal userland driver for Intel
* network card, only providing access to PCI BAR to applications, and
* enabling bus master.
