From bdf252183e58654fcceedbf3fdcfd878b9e4f2d6 Mon Sep 17 00:00:00 2001 From: Neerav Parikh Date: Mon, 16 May 2011 16:45:29 -0700 Subject: [SCSI] fcoe: Prevent creation of an NPIV port with duplicate WWPN This patch adds a validation step before allowing creation of a new NPIV port. It checks whether the WWPN passed for the new NPIV port to be created is unique for the given physical port.
