This reaches encapsulation for this file. In order to reach this:
 * move priv->valid_context to iwl_shared
 * move the last_rejected initialization to the upper layer
 * define a wrapper iwl_nic_config in the upper layer that calls to

41f5e0475c iwlagn: move traffic_log back to upper layer
The traffic log debugfs handlers were mistakenly moved to the
transport layer because they print the pointers of the Tx / Rx
queues. The pointers of the queues can be fetched by another debugfs
handler.
So bring the traffic log back to the upper layer and remove the part
that reads the Tx / Rx queues' pointers.

65e291acd8 iwlagn: merge iwl_pci_down and iwl_pci_remove
The latter was the only place that called the first. The two
functions were split when the iwl_pci_probe called iwl_pci_down
upon failure in the probe. Since iwl_pci_probe undoes its work by
itself, there is no need to split between iwl_pci_down, and
iwl_pci_remove.

996bc370fa b43: Relax requirement for descriptors to be in the DMA zone
When 64-bit DMA was first used, there were problems with the
BCM4311 (14e4:4311). The problem was "fixed" by using the GFP_DMA
flag in the allocation of coherent ring descriptor memory.

The original problem is now believed to have been due to bugs in
the 64-bit DMA implementation in the rest of the kernel, and that
those bugs have been fixed. Accordingly, the requirement for the
descriptors to be in the DMA zone is relaxed.

Bounce buffers are left in the DMA zone.

In order to implement support for GO powersave on
the P2P client side, the ucode needs to know what
GO we're trying to authenticate/associate with,
it needs to have a station entry and the BSSID in

Implement the new mac80211 callbacks to give this
data to the device.

Since this is also useful for the device when a
normal connection is established, also program it
with the information in that case.

464021ffc1 iwlagn: move the check_empty logic to the transport layer
This logic is responsible to tell mac80211 when the HW queues are
empty and the BA session can be started / torn down.

Fix a bug on the way:
When the the Tx BA session is stopped and the HW queues aren't empty,
we stop the SW queue to drain the HW queue and then switch to the
legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state.

While in this state, we never wake the SW queue, even when the HW
queue is almost empty, since we need to drain it completely. Look
at iwl_trans_pcie_reclaim regarding this.

Once the HW queue is really empty, we must wake the SW queue in order
to get traffic to the legacy queue.
This step was missing leading to an odd situation were the traffic
would just stall after we tore down a Tx BA session while the HW
queue was not empty.

5a878bf60b iwlagn: iwl_rx_queue moves to the iwl_trans_pcie
Since this struct is specific to pcie transport, move it the the pcie
specific transport layer.

87e5666c07 iwlagn: transport handler can register debugfs entries
Add a handler in iwl_trans_ops to allow it to add entries under debugfs dir
given by the upper level.

e6bb4c9c00 iwlagn: bus layer chooses its transport layer
Remove iwl_transport_register which was a W/A. The bus layer knows what
transport to use. So now, the bus layer gives the upper layer a pointer to the
iwl_trans_ops struct that it wants to use. The upper layer then, allocates the
desired transport layer using iwl_trans_ops->alloc function.

As a result of this, priv->trans, no longer exists, priv holds a pointer to
iwl_shared, which holds a pointer to iwl_trans. This required to change all the
calls to the transport layer from upper layer. While we were at it, trans_X
inlines have been renamed to iwl_trans_X to avoid confusions, which of course
required to rename the functions inside the transport layer because of
conflicts in names. So the static API functions inside the transport layer
implementation have been renamed to iwl_trans_pcie_X.

Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is
confusing since the registration doesn't mean to request IRQ, so I added a
handler for that.

44856c6596 iwlagn: modify the debug macro to be usable by all the layers
Since all the layers need to print debug message, the debug macro cannot suppose
that they will be given iwl_priv as a parameter and then dereference it.
Use iwl_shared instead.
