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.

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.

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.

Fixes:
- iwlwifi is an optional driver and should thus not default to 'y'.
- 3945 now depends on IWLCORE.
Rework:
- There is not a case when IWLCORE should not be selected. At the same time
the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of
these two. With IWLWIFI being the driver name we proceed to use just it and
replace instances of IWLCORE with it. The module name does not change
and is still iwlcore.
- Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move
this up to one select when IWLWIFI is selected.
- IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series.
- Now that 3945 depends on IWLWIFI we can also indicate its dependency on
MAC80211_LEDS and LEDS_CLASS at this level.
- IWLAGN_LEDS is not used by driver - remove it.
- IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part
of iwlcore module. Move this config up in Kconfig to reflect that and also
change name to IWLWIFI_SPECTRUM_MEASUREMENT.
- CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to
description that indicates this.
- CONFIG_IWL3945_RFKILL does not exist - remove usage from driver.
- Add "iwlagn" to end of description of IWLAGN to help people understand
what iwlagn means in rest of Kconfig text.
- Add "iwl3945" to end of description of IWL3945 to help people understand
what iwlagn means in rest of Kconfig text.
- Change IWLWIFI_DEBUGFS description to indicate that only iwlagn supports
it (for now).

The remaining uses of tg3_nvram_read_swab() either intended to read the
data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper
interpretations of the data. For the former case, a direct replacement
of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order. For
the latter case, we remove tg3_nvram_read_swab() and document what the
code is really doing.

Any software requesting NVRAM data as it exists on NVRAM is necessarily
requesting that the results be returned as a bytestream. A bytestream
data read in from the device can also be thought to be in big endian
format. Therefore, all the LE notations in the driver are mislabeled.
This patch converts all LE notations to BE notations, carefully
evaluating the surrounding code in the process.

This patch removes the blind byteswap of NVRAM data as it is read in.
To preserve the logic at the call sites, this patch also inverts every
call to tg3_nvram_read() and tg3_nvram_read_swab(). The call swap gets
confusing within tg3_nvram_read_le() (LE is a misnomer), but the reader
should be able to convince himself / herself that the resulting behavior
is still unchanged.

Disable the SSB core on device shutdown.
This has two advantages:
1) A clean device shutdown is always desired here, because we disable
the device's global crystal in the next statement.
2) This fixes a bug where the device will come up with the enable-bit
set on the next initialization (without a reboot inbetween).
This causes breakage on the second initialization due to code that
checks this bit (ssb_device_is_enabled() checks).

It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because
it has internal checks for redundant calls.

The mesh and radiotap interfaces need to use the same private data as
the main wifi interface. If the main wifi interface uses netdev_priv(),
but the other interfaces ->ml_priv, there's no way to figure out where
the private data actually is in the WEXT handlers and netdevice
callbacks. So make everything use ->ml_priv.
Fixes botched netdev_priv() conversion introduced by "netdevice
libertas: Fix directly reference of netdev->priv", though admittedly
libertas' use of ->priv was somewhat "special".
