2009-06-08[SCSI] lpfc 8.3.2 : Addition of SLI4 Interface - Base SupportJames Smart
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 Smart
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.

2007-06-17[SCSI] lpfc: NPIV: add NPIV support on top of SLI-3James Smart
NPIV support is added to the driver. It utilizes the interfaces of the fc transport for the creation and deletion of vports. Within the driver, a new Scsi_Host is created for each NPIV instance, and is paired with a new instance of a FC port. This allows N FC Port elements to share a single Adapter.

2007-06-17[SCSI] lpfc: NPIV: add SLI-3 interfaceJames Smart
NPIV support is only available via new adapter interface extensions, termed SLI-3. This interface changes some of the basic behaviors such as command and response ring element sizes and data structures, as well as a change in buffer posting. Note: the new firmware extensions are found only on our mid-range and enterprise 4Gig adapters - so NPIV support is available only on these newer adapters. The latest firmware can be downloaded from the Emulex support page. Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-06-17[SCSI] lpfc: NPIV: split portsJames Smart
The driver is reorganized to separate the handling of the adapter from the handling of the FC port. Adapter handling includes submissions of command requests, receiving responses, and managing adapter resources. The FC port includes the discovery engine, login handling, and the mapping of a Scsi_Host on the "port". Although not a large functional change, as it touches core structures and functions, resulting in a large text delta.
