With the hardware-specific code in place, add all supported device id's,
along with base driver changes to enable 82599 devices. The devices
being enabled are:
8086:10f7: 82599EB 10 Gigabit KX4 Network Connection
8086:10fb: 82599EB 10 Gigabit Network Connection
The device 8086:10fb is a fully-pluggable SFP+ NIC.

This patch adds the DCB (Data Center Bridging) support for 82599 hardware.
This is similar to how the 82598 DCB code works.
This patch also removes the BCN (Backwards Congestion Notification) netlink
configuration code from the driver. BCN was a pre-standard congestion
notification framework, and was not what the IEEE body decided upon for
standard congestion management. QCN (802.1Qau), Quantized Congestion
Notification is the accepted standard, which is not supported by 82599,
hence we remove the support altogether.

However, some may be extraneous.
The cancel_delayed_work call is probably the most necessary. The

be necessary either, but the Oops I was receiving was related to

Reset automatically the TSF on re-enabling beaconing after scanning
in IBSS mode causes several problems. For example a new created IBSS
network can't age before an other node has joined, because scans are
done automatically in that case. And several other strange bugs more...
The TSF reset is done manually in the higher level mac80211 code in
the cases were it's needed, so we don't need to do it here.

In the old days we used one slot per frame. But when we changed that to 2,
we didn't raise the overall slot count. Which resulted in an effective
division of two to the number of slots.
Double the number of TX slots, so we have an effective hardware queue
of 128 frames per QoS queue.
Also optimize the TX header cache handling. We don't need a cached TX header
for slots that will never carry an actual header.
So we reduce the memory consumption of the cache by 50%.
So as a net result we end up with more or less the same memory usage before
and after this patch (except a few tiny meta structures), but have twice
the number of TX slots available.

This fixes hidden bugs in the size handling of the DMA buffers.
This sets the RX buffer size to the theoretical max packet size and
fixes passing of the size values to the device (must not subtract the header offset).
These bugs are hidden and don't actually trigger due to the magic +100
offset for the buffer size.

When iwlwifi runs on IOMMU, IOMMU generates a lot of PTE write faults
because PTE write bit is not set on some of PTE's. This is because iwlwifi
driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping
PTE. But iwlwifi device actually writes to the mapped page to update its contents.
This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and
stop the fault transaction.
The iwl TX command contains a scratch field that is updated by uCode to
indicate retry counts. For 5000 series the patch is required also for
regular frames, but this patch does not differenciate.
