PCI drivers that implement the struct pci_error_handlers' error_detected callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is pci_channel_io_perm_failure. This patch fixes the issue for igbvf. Signed-off-by: Dean Nelson <redacted> --- This patch has not been tested, since I don't have the hardware to test it. It is based on a few recent patches.
