O-Subject: [RHEL5.5 PATCH 1/3 v3] lpfc: update version from 8.2.0.52 to 8.2.0.55
Bugzilla: 529244
https://bugzilla.redhat.com/show_bug.cgi?id=529244
Description from bz529244:
Patch to update Emulex lpfc driver to 8.2.0.55 (applies on top of
8.2.0.52, see Bug 515272).
This patch mainly adds AER support, as well as some additional fixes.
These are the changes included in this patch:
* Changed version number to 8.2.0.55
* Made AER sysfs entry point return "Operation not permitted" to
OneConnect HBAs
* Add support for Advanced Error Reporting (AER) feature support
for SLI3 PCIe HBA
* Fixed AER support is turned off by default (CR 94332)
* Made driver with AER support backward compatible to distribution kernels
that do not support AER.
* Changed version number to 8.2.0.54
* Fix send sequence logic to handle multi SGL IOCBs
* Fixed handling of unsolicited CT exchange initiator receiving CT exchange
ABTS
* Fixed ELS_ID bits added to ELS WQE FIP frames
* Fixed handling of unsolicited CT exchange sequence abort (uppper-level
driver part)
* Fixed handling of unsolicited CT exchange sequence abort (lower level
driver part)
* Changed version number to 8.2.0.53
* Fixed discovery failure during quick link bounce
* Add support for Clear Virtual Link
* Fixed Check for aborted els command
* Fix bug with missing new line characters in log messages (CR
94092)
* Fix bug with probe_one routines not putting the Scsi_Host back
upon error (CR 94088)
* Clear retry count in the delayed ELS handler
* Check the rsplen in lpfc_handle_fcp_err function before using
rsplen
* Removed the use of the locally defined FC transport layer related
macros
