The iwlwifi drivers go to great lengths to avoid passing packets to
mac80211 they think shouldn't go there, while mac80211 can (of course!)
handle them very well.
Especially in the case of duplicate packets this is interesting
because it's such a performance hog (especially for IBSS networks)
while mac80211 does that work on the side without much effort.
This patch removes all that and leaves only what is absolutely
necessary for the hardware.

trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.
this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.
for signal:
IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point
IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW
for noise we currently only have dBm:
IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW
if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.
i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

This
* makes the queue number passed to drivers a u16
(as it will be with skb_get_queue_mapping)
* removes the useless queue number defines
* splits hw->queues into hw->queues/ampdu_queues
* removes the debugfs files for per-queue counters
* removes some dead QoS code
* removes the beacon queue configuration for IBSS
so that the drivers now never get a queue number
bigger than (hw->queues + hw->ampdu_queues - 1)
for tx and only in the range 0..hw->queues-1 for
conf_tx.

This patch does 3 things
1) It removes the statistics work. The request statistics command is
sent in ASYNC mode in this flow, the mutex is uneeded, so the request
statistics function can't go to sleep. No need for a workqueue anymore.
2) iwl4965_send_statistics_request has been renamed to
iwl_send_statistics_request and moved to iwl-core.c
3) A request for statistics is sent in alive_notify, the makes the uCode
sends statistics notification periodically starting from association.
