With the mac80211 deauth sequence changes, the
station is deleted before the device is set
unassociated. This can cause the device to get
confused as it expects the station to be there
while the associated bit is set.
To fix this, do not delete the AP station from
the device when mac80211 asks for deletion,
instead just mark it as unused and rely on the
unassociated RXON to drop it from the station
database in the device.

The PASSIVE_NO_RX workaround currently crosses
through the op_mode and transport layers, which
is a bit odd. This also isn't necessary, if the
transport simply reports when queues are full
(or no longer full) the op_mode can keep track
of this state, and report to mac80211 only what
*it* thinks is appropriate. What is appropriate
can then be based on whether queues should be
stopped to wait for RX or not.
This significantly simplifies the transport API,
it no longer needs to expose anything to stop a
queue, nor to wake "any" queue, this can all be
handled in the upper layer completely.
Also simplify the handling to not be dependent
on the context, that makes little sense as the
queues are shared and both contexts have to be
on the same channel anyway.

When the command queue is full, the transport
will return -ENOSPC, but the reaction to that
depends on the op_mode. Virtualize that, the
DVM op_mode checks for CT-kill and restarts
the hardware otherwise.
We may be able to get rid of this callback by
putting the behaviour check into the wrapper
but that needs more careful evaluation.

Add wrappers to send commands from the DVM
op-mode (which essentially consists of the
current driver). This will allow us to move
specific sanity checks there.
Also, this removes iwl_trans_send_cmd_pdu()

DVM-specific wrapper.

Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.
Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.
Since I wanted to constify the firmware
pointers, some more changes were needed.

uCode loading belongs to the op_mode, as it
is dependent on various things there and the
commands sent during it are specific to it.

dependent after all).

My patch "iwlwifi: simplify auth/assoc flow"
caused a serious throughput degradation due
to me forgetting that there are HT settings
in the station table. To restore throughput,
set these parameters correctly when the sta
moves to assoc state.
This patch should probably be merged with
the auth/assoc redesign patch for upstream.
In that case, this paragraph should be added
to the commit log as the third paragraph
(before talking about RXON):
However, as we only get the station HT data
when the station moves into assoc state, we
also need to program this into the device
(and copy it into our database) then.

struct iwl_rx_mem_buffer implementation details
(DMA address, list pointers) that the upper
layers don't need. Introduce iwl_rx_cmd_buffer
that is passed upstream and only contains the
needed data (the page). Additionally, access
this data only via accessor functions, allowing
us to change the implementation in the future.
These accessors are rxb_addr() (as before) and
rxb_steal_page() to take ownership of the data.

With mac80211 now giving us station information
(via the sta_state callback) before auth/assoc
we can get rid of tx_sync by adding the station
early for the case of managed interfaces. Keep
AP mode actions the same for now.
As we now get the BSSID early, we can also get
rid of iwl_reprogram_ap_sta().
We can still optimise the number of RXONs we
send to the device, but that can be done later.

Before this patch, the upper layer could register a callback for each
host command. This mechanism allowed the upper layer to have
different callbacks for the same command ID. In fact, it wasn't used
and the rx_handlers is enough: same callback for all the command with
a specific command ID.
The iwl_send_add_station needs the access the command that was sent
while handling the response (regardless if the command was sent in
SYNC or ASYNC mode). So now, all the handlers receive the host
command that was sent. This implies a change in the handler signature.

Move all the iwlXXX_abgn_cfg forward declaration to a separate file
so that iwl-pci.c doesn't need to include iwl-agn.h that includes
all iwl-dev.h
This allows to provide real encapsulation. Dereferencing iwl_priv
in the bus layer will now lead to a compilation error.

Now that the reclaim flow has been moved to the transport layer, a lot of
functions can be made static or don't need to be exported outside the transport
layer.
