    Subject[PATCH 3.13.y-ckt 11/85] PCI: Add VPD function 0 quirk for Intel Ethernet devices
    Date
    3.13.11-ckt28 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Mark Rustad <mark.d.rustad@intel.com>

    commit 7aa6ca4d39edf01f997b9e02cf6d2fdeb224f351 upstream.

    Set the PCI_DEV_FLAGS_VPD_REF_F0 flag on all Intel Ethernet device
    functions other than function 0, so that on multi-function devices, we will
    always read VPD from function 0 instead of from the other functions.
