From 7313326125c8da52a10780b5af3b290fa9498dcb Mon Sep 17 00:00:00 2001 From: John Soni Jose Date: Sat, 20 Oct 2012 04:44:49 +0530 Subject: [PATCH] [SCSI] be2iscsi: Fix Task Completion Event handling The completion events returned by adapter differs based on the adapter. This fix checks for the adapter type and process the completion event.
