If anyone has any objections, please let me know. ------------------ From: Mark Rustad 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.
