Signed-off-by version available at http://marc.info/?l=linux-scsi&m=126342842601776&w=2 From: George Kadianakis <desnacked {bomb} gmail {point} com> A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts. This patch restores lpfc's ability to support MSI-X/MSI interrupts that the "Addition of SLI4 Interface - Base Support" patch [2] broke. It reestablishes MSI-X as the default interrupt method and in case MSI-X is not supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx.
