From 2be21fa23169dcfdf2d599ed78df7adcd88fc99a 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.
