Not that I would *like* to fix this, but I *need* to fix it. We are using
CentOS 6.5, which I believe is based on RHEL. We have kernel
I realize that we need to add/change ifdefs around pci_num_vf,
pci_intx_mask_supported, and pci_check_and_mask_intx in igb_uio/compat.h.
Any more specific suggestions on how to (elegantly) fix it for us, but not
break it for anyone else?
