Subject: [scsi] qla2xxx: add support for npiv
Message-id: 20071218030337.6087.48369.sendpatchset@shell.boston.redhat.com
O-Subject: [Bug 249618][QLogic][RHEL 5.2 feat 1/2]qla2xxx - Add NPIV for Fibre Channel virtual nPorts
Bugzilla: 249618
BZ 249618, part 1 of 2.
This patch provides support for NPort ID Virtualization, NPIV.
It builds cleanly on 2.6.18-53.el5 with the previous 3 QLogic
patches applied.
It is tested at the factory and by other vendors. It requires
the related firmware patch ( part 2 of this patch ) and switch
support for NPIV.
Upstream commits -
2c3dfe3f6ad8daff5acdb01713e4f2b116e78136:
[SCSI] qla2xxx: add support for NPIV
Following patch adds support for NPIV (N-Port ID Virtualization) to the
qla2xxx.
- supported within switched-fabric topologies only.
4d0ea24769c81581b8fd25fd7deff281b1b97dee:
[SCSI] qla2xxx: Retrieve max-NPIV support capabilities from FW.
