From 1bd49b482077e231842352621169dedff1f41931 Mon Sep 17 00:00:00 2001 From: Vasu Dev Date: Fri, 25 May 2012 10:26:43 -0700 Subject: [PATCH] [SCSI] libfc, fcoe, bnx2fc: cleanup fcoe_dev_stats The libfc is used by fcoe but fcoe agnostic, and therefore should not have any fcoe references. So renaming fcoe_dev_stats from libfc as its for fc_stats. After that libfc is fcoe string free except some strings for Open-FCoE.org.
