scsi: lpfc: Add Buffer to Buffer credit recovery support

2017-08-25T02:29:43Z

Add Buffer to buffer credit recovery support to the driver. This is a negotiated feature with the peer that allows for both sides to detect dropped RRDY's and FC Frames and recover credit.

Add Fabric assigned WWN support.

2017-04-24T07:25:49Z

Adding support for Fabric assigned WWPN and WWNN. Firmware sends first FLOGI to fabric with vendor version changes. On link up driver gets updated service parameter with FAWWN assigned port name. Driver sends 2nd FLOGI with updated fawwpn and modifies the vport->fc_portname in driver. Note: Soft wwpn will not be allowed when fawwpn is enabled.

scsi: lpfc: NVME Initiator: Base modifications

2017-02-22T23:41:43Z

NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch.
