John Fastabend 3b3bf3b92b ixgbe: remove unused fcoe.tc field and fcoe_setapp()
The fcoe.tc field is no longer used so remove it. After
the field is removed there is no need to keep fcoe_setapp()
around so remove it as well. And finally we can get rid
of some DCB #ifdef's in the fcoe code.

Vasu Dev dadbe85ac4 ixgbe: setup per CPU PCI pool for FCoE DDP
Currently single PCI pool used across all CPUs and that
doesn't scales up as number of CPU increases, so this
patch adds per CPU PCI pool to setup udl and that aligns
well from FCoE stack as that already has per CPU exch locking.

Adds per CPU PCI alloc setup and free in
ixgbe_fcoe_ddp_pools_alloc and ixgbe_fcoe_ddp_pools_free,
use CPU specific pool during DDP setup.

Re-arranged ixgbe_fcoe struct to have fewer holes
along with adding pools ptr using pahole.

Yi Zou 68a683cf6a ixgbe: add support to FCoE DDP in target mode
Add support to the ndo_fcoe_ddp_target() to allow the Intel 82599 device to
also provide DDP offload capability when the upper FCoE protocol stack is
operating as a target.

Amir Hanania c600636bd5 ixgbe: work around for DDP last buffer size
A HW limitation was recently discovered where the last buffer in a DDP offload
cannot be a full buffer size in length. Fix the issue with a work around by
adding another buffer with size = 1.

Yi Zou 27ab76065c ixgbe: add a refcnt when turning on/off FCoE offload capability
The FCoE offload is enabled/disabled per adapter, but upper FCoE protocol
stack could have multiple FCoE instances created on the same physical network
interface, e.g., FCoE on multiple VLAN interfaces on the same physical
network interface. In this case we want to turn on FCoE offload at the first
request from ndo_fcoe_enable() but only turn off FCoE offload at the very last
call to ndo_fcoe_disable(). This is fixed by adding a refcnt in the per adapter
FCoE structure and tear down FCoE offload when refcnt decrements to zero.

Yi Zou d0ed89373f ixgbe: Add infrastructure code for FCoE large receive offload to 82599
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.
