Move xen patchset to new version's subdir.

[people/pmueller/ipfire-2.x.git] / src / patches / suse-2.6.27.31 / patches.drivers / qla2xxx-8.02.01.02.11.0-k9-update

From: David Wagner <david.wagner@qlogic.com>
Subject: qla2xxx: additional fixes/updates for SLES11
References: bnc#450197
    
Here's some additional updates/corrections to qla2xxx for SLES11.
Should apply cleanly to the beta6 driver sources.
    
   [PATCH 1/5] qla2xxx: Add ISP84xx firmware-update support.
   [PATCH 2/5] qla2xxx: Add CT/ELS passthru support.
   [PATCH 3/5] qla2xxx: Use correct value for max vport in LOOP topology.
   [PATCH 4/5] qla2xxx: Correction of struct qla_flt_location.
   [PATCH 5/5] qla2xxx: Update version number to 8.02.01.02.11.0-k9.

Corresponding upstream patches are queued in our local tree for
for the next merge window (post 2.6.28).
