Include offloaded FCoE data into total rx/tx statistics for 82599 so they
are properly reflected by ethtool or ifconfig.

Enable using FCoE redirection table feature in 82599. The FCoE
redirection table has maximum of eight entries, corresponding
to maximum of eight receive queues to be used for distributing
incoming FCoE packets. This patch sets up the FCoE redirection
table when multiple receive queues are available for FCoE.

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 infrastructure code for FCoE Tx side offload feature to
82599, including Fiber Channel CRC calculation, auto insertion of
the start of frame (SOF) and end of frame (EOF) of FCoE packets,
and large send by FCoE Sequence Offload (FSO).

This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch
only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599.
In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add
support of FCoE offload features to 82599.
