NAME
pci_reset_function - quiesce and reset a PCI device function
SYNOPSIS
int pci_reset_function(struct pci_dev * dev);
ARGUMENTS
dev
PCI device to reset
DESCRIPTION
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.
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.
Returns 0 if the device function was successfully reset or negative if the device doesn't
support resetting a single function.
