While testing the station with the NIC 1000 family, it is found that
the plcp error can easily exceed 50 value in 100mSecs. This creates
unneccessary radio reset/tuning. This patch raises the PLCP error
threshold of the NIC 1000 from 50 to 200 error count.

To ensure that card is in a sane state during probe we add a reset call.
This change was prompted by users of kdump who was not able to bring up the
wireless driver in the kdump kernel. The problem here was that the primary
kernel, which is not running at the time, left the wireless card up and
running. When the kdump kernel starts it is thus possible to immediately
receive interrupts from firmware after registering interrupt, but without
being ready to deal with interrupts from firmware yet.

There is a problem if an "internal short scan" is in progress when a
mac80211 requested scan arrives. If this new scan request arrives within
the "next_scan_jiffies" period then driver will immediately return success
and complete the scan. The problem here is that the scan has not been
fully initialized at this time (is_internal_short_scan is still set to true
because of the currently running scan), which results in the scan
completion never to be sent to mac80211. At this time also, evan though the
internal short scan is still running the state (is_internal_short_scan)
will be set to false, so when the internal scan does complete then mac80211
will receive a scan completion.
Fix this by checking right away if a scan is in progress when a scan
request arrives from mac80211.

Error checking for aggregation frames should go into aggregation queue,
if aggregation queue not available, use legacy queue instead.
Also make sure the aggregation queue is available to activate,
if driver and mac80211 is out-of-sync, try to disable the queue and
sync-up with mac80211.

Provide the function to perform different type of uCode reset/reload operation.
When uCode detect error and can not fix itself, this iwl_force_reset()
function allow driver to perform the necessary reset/reload functions and help
to bring uCode back to normal operation state.
Currently only 2 type of force reset are available:
- reset radio
- reload firmware

Break the largish case for handling receive checksum into a separate
function, and if there is a problem use dev_XXX routines to
show which hardware is the problem.
Turn one corner case into a BUG(). This only happens if the driver
is expecting one behavior but the chip does the old behavior;
only ever saw this when bringing up a new chip type and driver
was buggy.

Change the resume path to use pci write config for a couple of reasons:

2. better to toggle this register on all chip types, since that

The fec driver was enabling receive buffer descriptor without allocating
the buffers. Make sure the buffer descriptors are initialized to not
start receiving packets.
Open also calls fec_restart after the rx buffers are allocated. With the code
in fec_restart, it zeroes out the buffer descriptors that have just been
setup.

This patch fixes two potential races in the velocity driver:
* Move the ACK and error handler to the interrupt handler. This fixes a
potential race with shared interrupts when the other device interrupts
before the NAPI poll handler has finished. As the velocity driver hasn't
acked it's own interrupt, it will then steal the interrupt from the
other device.
* Use spin_lock_irqsave in velocity_poll. In the current code, the
interrupt handler will deadlock if e.g., the NAPI poll handler is
executing when an interrupt (for another device) comes in since it
tries to take the already held lock.
Also unlock the spinlock only after enabling the interrupt in
velocity_poll.
The error path is moved to the interrupt handler since this is where the
ISR is checked now.

Currently, PAE frames are not assigned proper sequence numbers.
Since sending PAE frames as part of aggregates breaks
crupto with several APs, they are sent as normal MPDUs.

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset). As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.
Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.
