This adds infrastructure code for FCoE Rx side offload feature to
82599, which provides large receive offload for FCoE by Direct
Data Placement (DDP). The ixgbe_fcoe_ddp_get() and ixgbe_fcoe_ddp_put()
pair corresponds to the netdev support to FCoE by the function pointers
provided in net_device_ops as ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done.
The implementation of these in ixgbe is shown in the next patch.

This adds the FCoE feature header ixgbe_fcoe.h to 82599. This header includes
the defines and structures required by the ixgbe driver to support various
offload features in 82599 for Fiber Channel over Ethernet (FCoE). These offloads
features include Fiber Channel CRC calculation, FCoE SOF/EOF auto insertion,
FCoE Sequence Offload (FSO) for large send, and Direct Data Placement (DDP)
for large receive.
