Re-activate the interface on fc event HBA_EVENT_LIP_RESET_OCCURRED, this action restarts the vlan discovery on the real interface and in case the new vlan is discovered then its new interface is created. This allows creation of fcoe interface on vlan change causing HBA_EVENT_LIP_RESET_OCCURRED on Clear Virtual Link.
