iwl_power_initialize() initializes driver data (not device hardware), and does
not need to execute more than once (when the driver initializes). Therefore, it
does not belong in iwl3945_apm_init(), which initializes hardware, and may run
more than once.
Move it to iwl3945_pci_probe(), where it will run only once. This agrees
with similar placement in iwl-agn.c's iwl_pci_probe(), although placement
under "services" seemed more appropriate than under "mac80211".

The iwlwifi drivers have LED blinking requirements that
mac80211 cannot fulfill due to the use of just a single
LED instead of different ones for TX, RX, radio etc.
Instead, the single LED blinks according to transfers
and is solid on the rest of the time. As such, having
LED class devices registered that mac80211 triggers are
connected to is pointless as we don't use the triggers
anyway.
Remove all the useless code and add hooks into the
driver itself. At the same time, make the LED code
abstracted so the core code that determines blink rate
etc. can be shared between 3945 and agn in iwlcore.
At the same time, the fact that we removed the use of
the mac80211 LED triggers means we can also remove the
IWLWIFI_LEDS Kconfig symbol since the LED support is
now self-contained.

Adjust led blink rate to compensate on a MAC Clock difference on every

5% on 4965 HW and 20% on 5000 series and up.
Need to compensate on the led on/off time per HW according to the
deviation to achieve the desired led frequency
The calculation is: (100-averageDeviation)/100 * blinkTime
For code efficiency the calculation will be:
compensation = (100 - averageDeviation) * 64 / 100
NewBlinkTime = (compensation * BlinkTime) / 64

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.
This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.
Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

The field called 'len' in struct iwl_rx_packet is in fact not just a length
field but also includes some flags from the flow handler. In several places
throughout the driver, this causes incorrect values to be interpreted as
lengths when the field is improperly masked.
In most situations the improper use is for debugging output, and simply results
in an erroneous message, such as:
[551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620).
which should read '(480 vs 484)'.
In at least one case this could case bad things to happen:
void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv,
struct iwl_rx_mem_buffer *rxb)
{
struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data;
IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled "
"notification for %s:\n",
le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd));
iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len)
);
}
EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif);
Given the rampant misuse of this field without proper masking throughout the
driver (every use but one), this patch renames the field from 'len' to
'len_n_flags' to reduce confusion. It also adds the proper masking when
this field is used as a length value.

Commit "iwlwifi: make debug level more user friendly" cleaned up the
debug level handling. In doing so it created a single global debug
level for all devices. Some setups do consits of more that one iwlwifi
device and in these setups there is a requirement that debug levels
should be unique per device.
We now re-introduce the per device debugging while maintaining the
cleanup effort of the previous patch.
The maintain the global debug level and now introduce a per-device debug
level that will be used if it (the per-device debug level) is set. The
per-device debug level can be controlled via the debug_level sysfs file
while the global debug level is controlled by the debug module parameter.

The current command sending in iwlwifi is a bit of a mess:
1) there is a struct, iwl_cmd, that contains both driver
and device data in a single packed structure -- this
is very confusing
2) the on-stack data and the command metadata share a
structure by embedding the latter in the former, which
is also rather confusing because it leads to weird
unions and similarly odd constructs
3) each txq always has enough space for 256 commands,
even if only 32 end up being used
This patch fixes these things:
1) rename iwl_cmd to iwl_device_cmd and keep track of
command metadata and device command separately, in
two arrays in each tx queue
2) remove the 'meta' member from iwl_host_cmd and only
put in the required members
3) allocate the cmd/meta arrays separately instead of
embedding them into the txq structure

* Deprecate the "debug50" module parameter used to obtain
5000 series and up debugging. Replace it with "debug" module
parameter to match with original driver and be consistent
between them. The "debug50" module parameter can still be used,
except that the module parameter is not writable in keeping
with its previous state. We currently just mark it as "deprecated"
and do not have it in the feature-removal-schedule. Some more
cleanup of module parameters needs to be done and can then be
entered together.
* Only make "debug" module parameters visible if the driver
is compiled with CONFIG_IWLWIFI_DEBUG. This will eliminate
a lot of confusion where users think they have set debug flags
but yet cannot see any debug output.
* Make module parameters writable. This eliminates the need for the
"debug_level" sysfs file, which can now also be deprecated and
added to feature-removal-schedule. This file is in significant
use though with many iwlwifi documents and text referring users
to it. We can thus not take its removal lightly and keep it around.
With iwlcore shared between iwlagn and iwl3945 we really do not need
debug module parameters for each but can instead have one debug
module parameter for the iwlcore module. The same issue is here as
with the sysfs file - a lot of iwlwifi documentation and text (like
bug reports) rely on iwlagn and iwl3945 having this module parameter,
so changing this to a module parameter of iwlcore will have significant
impact and we do not do this for that reason.
One consequence of this patch is that if a user is running a system
with both 3945 and later hardware then the setting of the one module
parameter will affect the value of the other. The likelihood of this
seems low - and even if this setup is present it does not seem like an
issue for both modules to run with the same debug level.

A few issues wrt DMA were uncovered when using the driver with swiotlb.
- driver should not use memory after it has been mapped
- iwl3945's RX queue management cannot use all of iwlagn because
the size of the RX buffer is different. Revert back to using
iwl3945 specific routines that map/unmap memory.
- no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single,
we can just call pci_unmap_single initially
- only map the memory area that will be used by device. this is especially
relevant to the mapping of iwl_cmd. we should not map the entire
structure because the meta data at the beginning of structure contains
the address to be used later for unmapping. If the address to be used for
unmapping is stored in mapped data it creates a problem.
- ensure that _if_ memory needs to be modified after it is mapped that we
call _sync_single_for_cpu first, and then release it back to device with
_sync_single_for_device
- we mapped the wrong length of data for host commands, with mapped length
differing with length provided to device, fix that.

This patch removes all the virtual A-MPDU-queue bookkeeping from
mac80211. Curiously, iwlwifi already does its own bookkeeping, so
it doesn't require much changes except where it needs to handle
starting and stopping the queues in mac80211.
To handle the queue stop/wake properly, we rewrite the software
queue number for aggregation frames and internally to iwlwifi keep
track of the queues that map into the same AC queue, and only talk
to mac80211 about the AC queue. The implementation requires calling
two new functions, iwl_stop_queue and iwl_wake_queue instead of the
mac80211 counterparts.

So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific
ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host
commands, since the command length as to be set according to the HW. As
another precaution the reserved4 and reserved5 fields are cleared before being
sent to the 3945.
With the *39_rxon removal, a lot of duplicated code can be removed from the
3945 code base.

IWL3945_DEBUG is pointless and obsolete. We already have an IWLWIFI_DEBUG
symbol, that needs to be set if we actually want to get 3945 debug (see
iwl-debug.h).
Thus, we can simply get rid of this symbol.

By adding an additional hw_params (tfd_size) and a new iwl_lib ops (txq_init),
we can now use the iwlcore TX queue management routines.
We had to add a new hw_params because we need to allocate the right DMA buffer
for TFDs, and those have a different sizes depending if you're on 3945 or agn.

A warning message "MAC is in deep sleep" sometimes happen when user removes
the driver. This warning is related to card not being ready. In __iwl3945_down
function some of the going down steps are in wrong order, to fix this this patch
do the following:
1- make sure we are calling iwl3945_apm_reset and iwl3945_apm_stop
in the right order.
2- make sure we set CSR_GP_CNTRL_REG_FLAG_INIT_DONE in apm_reset before
poll on CSR_GP_CNTRL_REG_FLAG_MAC_CLOCK_READY.
3- set correct polling counter.

The TFD structures for 3945 and agn HWs are fundamentally different. We thus

Now that we're using iwl_mod_params, we want our module parameters names to be
in sync with the structure.
So, to set iwl_mod_params.sw_crypto, we'd better use a "swcrypto" parameter
name instead of the "hwcrypto" current one.
Moreover, by setting the decrypted flag properly, this patch also fixes the HW
crypto path for 3945 (the current code is not setting it when running HW
crypto).

This patch replaces the queue and channel info 3945 structures with the iwl
ones.
The initial goal was to replace the channel info structure. Once we do that,
and then include iwl-dev.h instead of iwl-3945.h, we still get build errors
due to several routines and macro redefinitions. This is why this patch also
includes:
- TFD39_MAX_PAYLOAD definition for 3945.
- CMD_SIZE, CMD_HUGE, CMD_SKB duplication removal.
- iwl3945_queue replacement in order to also get rid of the duplicated
get_cmd_index routine.
Getting rid of any of those needs the iwl-dev.h inclusion which then creates
build errors due to definitions duplication. This is why we include all those
in the same patch.
