Porting FreeBSD driver from 8.4 to 10.3 - PCI_ENABLE_MSI definition missing

[Reguna, Lakshmi]

Hi,

I am attempting to port a freebsd driver from 8.4 to 10.3. I ran into the following compilation error. I am not able to find any file which declares PCI_ENABLE_MSI,   PCI_ENABLE_MSIX, PCI_DISABLE_MSI etc. The actual definition of PCI_ENABLE_MSI seems to point to  pci_enable_msi_method in pci.c. Any thoughts on what might be missing ?

               DEVMETHOD(pci_enable_msi,     pci_enable_msi_method),


Build Error:

@/dev/pci/pcivar.h:459:5: error: implicit declaration of function 'PCI_ENABLE_MSI' is invalid in C99
