From e6a010da87cf64f5fe4ee60718db7dc73d2299e1 Mon Sep 17 00:00:00 2001 From: Saurav Kashyap Date: Tue, 15 May 2012 14:34:16 -0400 Subject: [PATCH] [SCSI] qla2xxx: Stats should be different from physical and virtual ports Currently stats is part of ha data structure, common for physical and virtual ports. Moved the stats to vha, each port will have its own stat.
