[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: Added support to collect and reset fcport stats

2011-07-27T10:48:52+00:00

- Added support to collect and reset fcport stats.
- Modified design to allow multiple requests for fcport stats.
  - fcport will remember the stats request in its stats_pending
    queue and service each of the queued requests after receiving
    a firmware response for the prior request.

[SCSI] bfa: Added HBA diagnostics support.

2011-06-29T22:25:44+00:00

- Added diagnostics sub-module to BFA.
- Implemented interface to perform memtest/loopback test
  and some other diagnostics tests.

[SCSI] bfa: FCS bug fixes.

2011-06-29T22:12:11+00:00

- Added logic to initiate a PLOGI to the target, while processing a LOGO
  from the same target in Direct attach mode.
- Added logic to generate a FCCT Reject indicating unsupported command,
  upon receiving FCCT/FCGS requests.
- Added logic to set the fcpim in offline state and avoid any PRLI retries
  if a PRLI response is a reject with a reason Command Not Supported.
- Updated the FDMI Supported/Current speeds.
- Added logic to wait for the response  from the firmware before sending
  ACC to PLOGI and transitioning to subsequent states - while processing an
  Incoming PLOGI in online state.
- Added a wait state in the fcs_vport state machine - For case where
  FDISC is in progress and we get a vport delete request we wait for
  fdisc response and will transition to the appropriate state based on
  rsp status, else its causing both driver/fw resources to be not
  freed.
- Remove the fc_credit_recovery module param.

[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.

[SCSI] bfa: Added Fabric Assigned Address(FAA) support

2011-06-29T21:59:01+00:00

- Updated/added data structures and definitions to support FAA protocol.
- Modified the IOC state machine to support FAA.
- Introduced FAA feature configuration - enable/disable/query.
