Subject: [SCSI] qla2xxx: Do not enable VP in non fabric topology.
X-Git-Tag: v2.6.36-rc1~570^2~239
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3f3b6f98cb33043cba04f45a2f2c43b8303c120c;p=karo-tx-linux.git

[SCSI] qla2xxx: Do not enable VP in non fabric topology.

After topology change ISP is reset and VPs are re-enabled.
If the topology is not fabric, VPs could falsely get enabled.
