bf6aede712 workqueue: add to_delayed_work() helper function
It is a fairly common operation to have a pointer to a work and to need a
pointer to the delayed work it is contained in.  In particular, all
delayed works which want to rearm themselves will have to do that.  So it
would seem fair to offer a helper function for this operation.

99b7623380 proc 2/2: remove struct proc_dir_entry::owner
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

e4e72fb4de mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifi
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.

b1720231ca mac80211: unify and fix TX aggregation start
When TX aggregation becomes operational, we do a number of steps:
 1) print a debug message
 2) wake the virtual queue
 3) notify the driver

Unfortunately, 1) and 3) are only done if the driver is first to
reply to the aggregation request, it is, however, possible that the
remote station replies before the driver! Thus, unify the code for
this and call the new function ieee80211_agg_tx_operational in both
places where TX aggregation can become operational.

Additionally, rename the driver notification from
IEEE80211_AMPDU_TX_RESUME to IEEE80211_AMPDU_TX_OPERATIONAL.

b726604706 ath5k: warn and correct rate for unknown hw rate indexes
ath5k sets up a mapping table from the hardware rate index to
the rate index used by mac80211; however, we have seen some
received frames with incorrect rate indexes.  Such frames
normally get dropped with a warning in __ieee80211_rx(),
but it doesn't include enough information to track down the
error.

This patch adds a warning to hw_to_driver_rix for any lookups
that result in a rate index of -1, then returns a valid rate so
the frame can be processed.

3e3ccb3d9b b43: Mask PHY TX error interrupt, if not debugging
This masks the PHY TX error interrupt, if debugging is disabled.

Currently we have a bug somewhere which triggers this interrupt once
in a while. (Depends on the network noise/quality). While this is nonfatal,
it scares the hell out of users and we frequently receive bugreports
that incorrectly identify this error message as the reason.

There's another problem with this. The PHY TX error interrupt is protected
with a watchdog that will restart the device if it keeps triggering very often.
This is used to fix interrupt storms from completely broken devices.

However, this watchdog might trigger in completely normal operation.
If the TX capacity of the card is saturated, the likeliness of the watchdog
triggering increases, as more TX errors occur. The current threshold
for the watchdog is 1000 errors in 15 seconds.

This patch adds a workaround for the issue by just enabling the interrupt
if debugging is disabled (by Kconfig or by modparam).

This has the downside that real fatal PHY TX errors are not caught anymore.
But this is nonfatal due to the following reasons:
* If the card is not able to transmit anymore, MLME will notice anyway.
* I did _never_ see a real fatal PHY TX error in a mainline b43 driver.
* It does _not_ result in interrupt storms or something like that.
  It will simply result in a stalled card. It can be debugged by enabling
  the debugging module parameter.

0934af2340 ath9k: Fix rate control update for aggregated frames
We will miss rate control update if first A-MPDU of an
aggregation is not Block Acked as we always tell if the
rate control needs to updated through update_rc of first
A-MPDU. This patch does rate control update for the first
A-MPDU which notifies it's tx status (which is not
necessarily the first A-MPDU of an aggregation) to mac80211.

Control the rate decrease. Do not decrease the rate fast.
Use success_ratio for rate scaling :)
