Subject: [PATCH 5/8] lpfc 8.2.2 : Miscellaneous management and logging mods
From: James Smart <James.Smart () Emulex ! Com>
Date: 2007-07-31 21:33:08
Message-ID: 1186067421.14374.22.camel () localhost ! localdomain
[Download RAW message or body]
Miscellaneous management and logging mods:
- Remove the "management_version" sysfs parameter (was unused)
- Add HBQ information to lpfc debugfs
- Change lpfc_npiv_enable name back to lpfc_enable_npiv (internal stds)
- Remove "issue_lip" attribute from the vports transport template
