[SCSI] bfa: Introduced initiator based lun masking feature.

2011-07-27T10:55:03+00:00

- Added support to enable initiator based lun masking.
- Initiator based Lun masking works similar to zoning where
  initiator port is allowed to see only those LUNs which are
  configured to be seen.

[SCSI] bfa: DMA memory allocation enhancement.

2011-06-29T22:11:09+00:00

- Modified the design such that each BFA sub-module will provide
  the amount of DMA and KVA memory needed by it and queues the
  same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
  the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
  needed by all the BFA sub-modules as one contiguous chunk.

[SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.

2011-06-29T22:02:28+00:00

- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
  from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
  in the message header and firmware modules use h/w queue ID from
  message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
  Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI
  messages.  Used to translate host tag to firmware tag. bfa_lpuid()
  is changed to bfa_fn_lpu() that encodes both PCI function and port
  ID in BFI message header.
