0c325769a3 iwlagn: move ISR related data to transport layer
Since the ISR is entirely in the transport layer, its data should be in the pcie
specific region.
Change sync_irq to first disable and then synchronize the IRQ.
iwl_isr and iwl_isr_ict now receive iwl_trans.

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.

cac988a682 iwlagn: introduce struct iwl-shared - known by all layers
This struct will hold pointers to all the layers, so that every layer will find
the pointers it needs when calling another layer.

Note that the drv_data set to struct device is now a pointer to
struct iwl_shared.
This solves of bug that I introduced in

	iwlagn: simplify the bus architecture

Bug description:

sysfs gets the the driver data from struct device. Till the aforementioned
patch, dev_get_drvdata would return iwl_priv. After the patch, dev_get_drvdata
return iwl_bus which is buggy since the sysfs handlers rely on this value, and
sysfs handlers need iwl_priv.

Now, dev_get_drvdata return iwl-shared. Since we have pointers to all the
layers in iwl_shared, every layer will be able to get the pointer it needs:
bus layer will gets iwl_bus from the PCI suspend callbacks, and the sysfs
handlers will get the iwl_priv they need.

In order to keep good encapsulation, we need to avoid to dereference iwl_priv
from a different layer. This is why instead of including iwl-dev.h from
iwl-shared.h, I added a forward declaration to iwl_priv. Moreover we keep type
safety while providing encapsulation.

5d7969bf2b iwlagn: separate firmware version warning
We sometimes need to support new firmware API for
a while before we can publish them since testing
them fully takes a long time. We could keep all
the new code private, but that causes plenty of
problems and sometimes we can give a pre-release
version of firmware to people who need to test.
However, when we just bump the API version, the
driver will warn everybody that their firmware is
outdated, when in fact it isn't. (Currently our
case for this doesn't really change the API but
bumping the API version is necessary because the
firmware isn't fully backward compatible)

In order to handle this in the future, add a new
"api_ok" version; only below this will the driver
warn that the uCode is too old.

c8ac61cf6e iwlagn: implement WoWLAN
Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do
GTK rekeying when asleep (if HW crypto is used).
Unfortunately, we need to disconnect from the AP
after resume since we can't yet get all the info
out of the wowlan uCode to stay connected safely.

5a3d9882b8 iwlagn: rewrite HW crypto
As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).

To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.

Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.

Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

d593411084 iwlagn: simplify the bus architecture
Call iwl_probe with a ready iwl_bus struct. This means that the bus layer
assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to
iwl_probe.

The device specific struct is allocated together with the common iwl_bus struct
by the bus specific layer. The pointer to the aggregate struct is passed to the
upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.

Provide bus_* inliners on the way in order  to simplify the syntax.

Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the
external of the bus layer.

207ecc5eab iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic state
WiFi throughput drops drastically when BT is turned on, BT and WiFi
are simultaneously transmitting/receiving traffic. This is particularly true
when BT has higher priority over WiFi, and hence the device defers TX frames.
The AP assumes that the channel is bad and reduces the data rate, implying
longer airtime, which exacerbates the problem further, resulting ultimately
in what is popularly called the "death-spiral" phenomenon. The use of PS-poll
in such scenarios guarantees a low but consistent throughput.

Since the death-spiral phenomenon is observed only when the RSSI is low, use
PS-poll only when RSSI is low and disable when high, with a known hysterisis.

This feature specifies the high and low thresholds and implements the
callbacks registered with mac80211, which will be called when threshold events
occur.

1359ca4f30 iwlagn: add an API to free the TX context
Tx free functions move to the transport layer. Unify the functions that deal with tx queues and cmd queue.

Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different.
iwlagn_txq_free_tfd receives now the index of the TFD to be freed, which allows to unify the release flow for all the queues.

The transport layer is responsible for all the queues, DMA rings etc...
This is the beginning of the separation of all the code that is tighly
related to HW design to the aforementioned transport layer.
