[SCSI] bnx2fc: Validate vlan id in NETDEV_UNREGISTER handler
Nithin Nayak Sujir [Tue, 30 Aug 2011 22:54:50 +0000 (15:54 -0700)]
When bnx2fc receives an UNREGISTER event on a vlan interface it calls
destroy on all interfaces that matches the physical interface. Add
vlan_id check to destroy only the vlan interface that generated the
event.
