vxge: Fixed MSIX interrupt configuration.
- Fixed MSIX interrupt configuration to support non contiguous vpaths in
functions. Four msi-x vectors are reserved per vpath internal to the chip.
In all, there are 68 msi-x vectors for the 17 vpaths in the chip. In the
multi function configurations, non-contiguous vpaths are configured to
represent a function. For instance vpaths 0 and 8 can be configured to
represent function zero.
- If pci_enable_msix fails for the requested vectors, try with a lesser number
vectors by reducing the vpath count.
