		IPsec Offload
		-------------
		The ixgbe driver supports IPsec Hardware Offload. When creating Security
		Associations with "ip xfrm ..." the 'offload' tag option can be used to
		register the IPsec SA with the driver in order to get higher throughput in
		the secure communications.

		The offload is also supported for ixgbe's VFs, but the VF must be set as
		'trusted' and the support must be enabled with::

		ethtool --set-priv-flags eth<x> vf-ipsec on
		ip link set eth<x> vf <y> trust on
