On the disassociation event from the mac80211, the wl12xx driver does not
clear the chipset configuration related to the AP - i.e. it does not perform
a DISCONNECT and then a JOIN with zero SSID and dummy BSSID. Also, it does not
unset the BSSID filter.
Often this is not a problem, as the above is performed upon entering idle
state. But if a scenario arises where a new association is attempted without
cycling through idle state, the new association will fail.
Fix this by resetting the firmware state on disassociation.

The wl1271_rx function loops through packets in an aggregated buffer. Each
packet in the buffer is handled by a call to wl1271_rx_handle_data, which will
fail if skb memory allocation fails or production mode is enabled. These
failures currently prevent the rx counters to be incremented, thus causing the
rx loop to run forever.
Fix this by ignoring error codes reported wl1271_rx_handle_data function.
This essentially means that frames will be dropped in production mode, which
is the intetion, and frames will be dropped if memory allocation fails, which
is a decent way to recover from that situation.

The number of entries in the TX queue is compared to the low watermark
value each time TX completion interrupts are handled.
However, the fact that a TX completion arrived does not necessarily mean
there are any less skbs in the TX queue.
In addition, a TX completion interrupt does not necessarily mean that there
are any new available TX blocks. Thus, queuing TX work when the low
watermark is reached might not be needed.
Fix this by moving the low watermark handling to the TX work function,

Fix up conflicts in net/core/dev.c, drivers/net/pcmcia/smc91c92_cs.c and
drivers/net/wireless/ath/ath9k/debug.c as per David
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Due to legacy reason, dating back to when the wl1251 and wl1271 still were

The hardware recovery code creates a scenario in which it is possible for a

which causes a kernel WARNing and a subsequent reboot.
To remedy this, move the work initialization calls to the hw allocation,

Currently then dwell times for each channel in scans is set to an overly

Based on testing, comparable results can be received with smaller dwell-time,
and, with fever probe-requests - in fact, reducing the number of probe-requests
to 2 seems to increase the number of found results.
Configure more optimal values for per channel dwell times. Comparison for the
different scan configurations (in my current office environment):

40000 3x probe-req == ~50 results
