From 7adc5a3746553971c13fdebc75d6ac1678638d94 Mon Sep 17 00:00:00 2001 From: Bhanu Prakash Gollapudi Date: Mon, 4 Jun 2012 16:15:44 -0700 Subject: [PATCH] [SCSI] bnx2fc: Support interface creation on non-VLAN interface also. bnx2fc had an assumption that the fcoe interface will always start on the vlan dev. However, some switch implementations (Eg., HP virtual connect FlexFabric) expects the fcoe interface to be started on physical interface. Do not error out if the netdev is not a vlan dev.
