Subject: [net-next PATCH 2/8] vlan: Add support for
	net_devices_ops.ndo_fcoe_enable/_disable to VLAN

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

This adds implementation of the net_devices_ops.ndo_fcoe_enable/_disable to
the VLAN driver. It checks if the real_dev has support for ndo_fcoe_enable/
ndo_fcoe_disable and if so, passes on to call the associated real_dev.
