From: Madhuranath Iyengar Date: Wed, 22 Dec 2010 00:00:18 +0000 (-0800) Subject: [SCSI] qla2xxx: Update FCP priority information to firmware before sending IOs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=21090cbe95189d4ce6135fc8fec2f416b3eb227f;p=linux-beck.git [SCSI] qla2xxx: Update FCP priority information to firmware before sending IOs The FCP priority info was not being updated properly in certain situations. Here are the changes that needs to be done to take care of this issue: 1. No need to check fcport->state for FCS_UNCONFIGURED in qla24xx_update_fcport_fcp_prio(), since an invalid loop id check is already performed which is sufficient. 2. Add the missing qla24xx_update_fcport_fcp_prio() function call within qla2x00_update_fcport() function, so that the priority info is updated on every port addition or change. 3. Perform proper adapter types checking. 4. Other changes, associated with DEBUG/printk's and parameter passing.
