mac80211 adds stations in HT IBSS as soon as a frame comes by,
even if the HT capabilities are not known yet (they are often
received later, e.g. in beacons). So far, ampdu factor/density
are only calculated when the station is initially added.
This patch changes this to update ampdu factor/density settings
when starting a blockack session.
Using this patch, we had performance boosts from 60 to 150 MBit/s
between two 2x2 Atheros devices in 5 GHz HT IBSS mode.

As recovery queuing can now occur from multiple code paths
it's convenient to know what triggered it in all cases
other than an intended recovery which is part of the
switch between single role to multi role.

Following the addition of propagating errors from the bus ops
there's a need to distinguish between bus errors (including timeout)
and a legitimate timeout occuring in cmd_wait_for_event_or_timeout.
In case of real bus errors we need to queue recovery even in cases
where a timeout on a response from the FW to a command is acceptable.

commit 14bba17b "wl12xx: Propagate errors from wl1271_raw_write32"
breaks down TX in certain scenarios. wl1271_irq_locked() propagates
errors from wl1271_tx_work_locked however it may return -EBUSY
when the FW queues are full which is a legitimate case and not a
a real error. In this case a recovery is triggered by wl1271_irq
and this keeps repeating itself so TX is completely broken.
Fix it by avoiding propagating return values as errors even if they
aren't. Only bus (SDIO or SPI) ops failures would be progagated
as only these should trigger recovery.

We need to release the IRQ if hw_info() or identify_chip() fails. And
we need unregister the HW with mac80211 if there are any failures
after it's registered.

The new PG2 version of the chip has a few differences in terms of FW
API if compared to PG1. PG1 is just a sample that shouldn't be used
in real life, so to avoid having to handle both separately, mark the
PG1 version as deprecated and bail out during probe.

The code is fine in both cases as-is, but we can
write it slightly differently to fix smatch/sparse
complaints:
* compare the skb pointer (which we use as a cookie)
by casting the skb to unsigned long rather than the
cookie to a pointer (fixes "different address spaces")
* when transmitting, data->channel must be assigned,
don't check it (fixes "dereferenced before check")

It can be very useful to have all debug messages
available when debugging, but hard to correlate
between different sources, so add a trace event
for all mac80211 debug messages.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
There are a few things that make the logging and
debugging in mac80211 less useful than it should
be right now:
* a lot of messages should be pr_info, not pr_debug
* wholesale use of pr_debug makes it require *both*
Kconfig and dynamic configuration
* there are still a lot of ifdefs
* the style is very inconsistent, sometimes the
sdata->name is printed in front
Clean up everything, introducing new macros and
separating out the station MLME debugging into
a new Kconfig symbol.

Take the mutex early in the resume handler and use the locked version of
the IRQ routine. This ensures any recoveries queued will only take place
after resume has fully completed.

Separate the threaded IRQ handling routine into two functions.
The outer function takes the mutex and calls recovery on errors. It also
performs a Tx-path optimization to avoid redundant works.
The inner function is simplified - all calls to recovery are removed and
it assumes the lock is taken. The locked variant will be reused elsewhere.

If an error is detected after mac80211 is already suspended, the recovery
work will not be queued. This will leave the driver in a bad state on
