2009-06-08[SCSI] lpfc 8.3.2 : Addition of SLI4 Interface - Mailbox handlingJames Smart1-8/+14
The mailbox commands themselves are the same, or very similar to their SLI3 counterparts. This patch genericizes mailbox command handling and adds support for the new SLI4 mailbox queue.

2009-06-08[SCSI] lpfc 8.3.2 : Addition of SLI4 Interface - Base SupportJames Smart1-155/+3645
Adds new hardware and interface definitions. Adds new interface routines - utilizing the reorganized layout of the driver. Adds SLI-4 specific functions for attachment, initialization, teardown, etc. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2009-06-08[SCSI] lpfc 8.3.2 : Reorganization for SLI4James Smart1-471/+1436
Preps the organization of the driver so that the bottom half, which interacts with the hardware, can share common code sequences for attachment, detachment, initialization, teardown, etc with new hardware. For very common code sections, which become specific to the interface type, the driver uses an indirect function call. The function is set at initialization. For less common sections, such as initialization, the driver looks at the interface type and calls the routines relative to the interface.

2008-12-29[SCSI] lpfc 8.3.0 : Add active interrupt test for enabling MSI/MSI-X/INTxJames Smart1-136/+274
Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.
