.SH "DESCRIPTION"
.PP
Some devices allow an individual function to be reset without affecting other functions in the same device\&. The PCI device must be responsive to PCI config space in order to use this function\&.
.PP
This function does not just reset the PCI portion of a device, but clears all the state associated with the device\&. This function differs from __pci_reset_function in that it saves and restores device state over the reset\&.
.PP
Returns 0 if the device function was successfully reset or negative if the device doesn\*(Aqt support resetting a single function\&.
