Subject: [net-next PATCH 06/12] vlan: Add support for
	net_devices_ops.ndo_fcoe_control to VLAN

From: Yi Zou <yi.zou@...el.com>

This adds implementation of the net_devices_ops.ndo_fcoe_control to the VLAN
driver. It checks if the real_dev has support for ndo_fcoe_control and pass on
to call the associated real_dev->netdevice_ops->ndo_fcoe_control.
