[SCSI] bfa: Fix WARN_ON condition check

2013-06-26T18:45:51+00:00

The WARN_ON condition check in IO completion path is wrong. IOtags
returned by the firmware is compared with driver/bfa iotag after masking
the retry count bits.

[SCSI] bfa: Add support for max target ports discovery

2012-09-24T08:10:57+00:00

- Changes to avoid discovering NPIV port as remote port by the other
  NPIV ports created on same physical port when all the NPIV ports are
  part of the same zone in a fabric.
- Provided mechanism to support maximum number of target ports for a
  given initiator port (physical port + NPIV ports) irrespective of the
  way in which the initiator and target ports are zoned in the fabric.
- Introduced module_parameter max_rport_logins to restrict number of
  remote ports discovery which includes target and initiator remote ports.

[SCSI] bfa: Fix possible NULL pointer dereference in lunmask add/delete.

2012-01-10T23:01:23+00:00

Patch fixes the possible NULL pointer dereference when we try to add or delete
a rpwwn to the lunmask config which is not zoned to this port.  Check if the
FCS rport is not NULL before de-referencing it.
