7a10e3e407 iwlagn: iwl-trans.c can't dereference iwl_priv any more
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
   cfg->lib->ops->nic_config

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.

debcf73428 iwlagn: handle GO powersave
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
the RXON set.

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.

the mapping tx_queue -> fifo is really transport related. The upper

Note that upon agg_disable, the queue is always mapped to fifo 0, but
this doesn't matter since when the queue will be setup again for a

1f7b6172db iwlagn: move isr_statistics to transport layer
It is accessed by the transport layer only, hence the move.
The debugfs handlers that accessed it moved to the transport layer too.
The rx_handlers part of it stayed in the upper layer and a special debugfs
has been added for it

Also add missing includes to iwl-commands.h.
