- * to PCI config space in order to use this function.
- *
- * The device function is presumed to be unused when this function is called.

- * random, so any caller of this must be prepared to reinitialise the
- * device including MSI, bus mastering, BARs, decoding IO and memory spaces,
- * etc.
- *
- * Returns 0 if the device function was successfully reset or negative if the
- * device doesn't support resetting a single function.
