2010-12-21T18:24:01+00:00

Added support for ELS RRQ command

- Add new routine lpfc_set_rrq_active() to track XRI qualifier state.

[SCSI] lpfc 8.3.13: FC Discovery Fixes and enhancements.

2010-07-27T17:01:31+00:00

- Retry PLOGI up to 48 times when LS_RJT reason is
  "Unable to supply requested data."
- When dev loss timeout occures do not change state if there
  is an outstanding REG_LOGIN.
- Add logic to ignore REG_LOGIN completion if discovery is
  restarted while waiting for REG_LOGIN.
- Only change state on REG_LOGIN completion if still in
  state waiting for REG_LOGIN completion.
- Only send ADISCs to FCP-2 Targets (not Initiators).

[SCSI] lpfc 8.3.1: misc fixes/changes

2009-04-27T14:42:47+00:00

8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Replaced repeated code segment for canceling IOCBs from a list with
  a function call, lpfc_sli_cancel_iocbs().

- Increased HBQ buffers to support 40KB SSC sequences.

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space
