Change Details

This fixes the interrupt behavior of controllers which has flakey MMIO behavior. For instance, SM961/PM961 SSDs are observed that the offsets starting from 0x3084 within the memory region specified by BAR0 are all read as 0. The changes are made in accord to the MSI-X implementation of Illumos kernel. Two non-exported functions are modified: pci_mask_msix() and pci_unmask_msix().
