Jouni Malinen 1965c85331 nl80211: Add event for authentication/association timeout
SME needs to be notified when the authentication or association
attempt times out and MLME has stopped processing in order to allow
the SME to decide what to do next.

Johannes Berg 04fe20372e mac80211: calculate maximum sleep interval
The maximum sleep interval, for powersave purposes, is
determined by the DTIM period (it may not be larger)
and the required networking latency (it must be small
enough to fulfil those constraints).

This makes mac80211 calculate the maximum sleep interval
based on those constraints, and pass it to the driver.
Then the driver should instruct the device to sleep at
most that long.

Note that the device is responsible for aligning the
maximum sleep interval between DTIMs, we make sure it's
not longer but it needs to make sure it's between them.

Also, group some powersave documentation together and
make it more explicit that we support managed mode only,
and no IBSS powersaving (yet).

Johannes Berg e255d5eb2b mac80211: remove IEEE80211_CONF_CHANGE_DYNPS_TIMEOUT
Just setting IEEE80211_CONF_CHANGE_PS should be sufficient
for changes in the power saving things. The driver already
tells us whether it wants notification of dynps via the
"have dynps support" hw flag.

Johannes Berg 1d4df3a50f mac80211: fix variable truncation on 32-bit
Stephen Rothwell reported these warnings from a 32-bit build:

  net/mac80211/mlme.c:1771: warning: left shift count >= width of type
  net/mac80211/mlme.c:1772: warning: left shift count >= width of type
  net/mac80211/mlme.c:1773: warning: left shift count >= width of type
  net/mac80211/mlme.c:1774: warning: left shift count >= width of type
  net/mac80211/mlme.c:1775: warning: left shift count >= width of type

This shows a bug in my code -- BIT(X) uses just "1 << X" which means
a 32-bit integer on 32-bit platforms, but the code here needs a u64
on all platforms. Fix this by using "1ULL << X" instead of BIT(X).

Thanks Stephen!

Jussi Kivilinna 8d4d99ae89 rndis_wlan: fix initialization order for workqueue&workers
rndis_wext_link_change() might be called from rndis_command() at
initialization stage and priv->workqueue/priv->work have not been
initialized yet. This causes invalid opcode at rndis_wext_bind on
some brands of bcm4320.

Fix by initializing workqueue/workers in rndis_wext_bind() before
rndis_command is used.

Abhijeet Kolekar 09f9bf79b7 iwlwifi: remove radio disable parameter.
Patch removes the "manual radio disable" parameter
as there is no usage scenario of disabling radio using this module parameter.
User can use iwconfig's txpower to enable and disable radio.

This module parameter also does not work as expected. During module load
the status of radio is set, the radio is not actually disabled. Even so,
the moment mac80211 requests the interface to be up the radio will be
enabled again.

Johannes Berg e7ec86f54e mac80211: validate TIM IE length (redux)
The TIM IE must not be shorter than 4 bytes, so verify that
when parsing it and use the proper type. To ease that adjust
struct ieee80211_tim_ie to have a virtual bitmap of size
at least 1.

Also check that the TIM IE is actually present before trying
to parse it!

Because other people may need the function, make it a static
inline in ieee80211.h.

(The original "mac80211: validate TIM IE length" was a minimal fix for
2.6.30.  This purports to be the full, correct fix. -- JWL)

The fact that these are exported is a technical detail
of the conversion period -- we don't want anybody to

Jouni Malinen b9a5f8cab7 nl80211: Add set/get for frag/rts threshold and retry limits
Add new nl80211 attributes that can be used with NL80211_CMD_SET_WIPHY
and NL80211_CMD_GET_WIPHY to manage fragmentation/RTS threshold and
retry limits.

Since these values are stored in struct wiphy, remove the local copy
from mac80211 where feasible (frag & rts threshold). The retry limits
are currently needed in struct ieee80211_conf, but these could be
eventually removed since the driver should have access to the values
in struct wiphy.

Johannes Berg 9e52b0623c ar9170: support HT receive and channel config
This patch adds support for configuring HT40 channels
and receiving HT40 to ar9170. Receiving aggregation
doesn't seem to work right now, so it's not enabled.
Same goes for TX aggregation, but that probably needs
even more work.

With this, I can receive roughly 33 Mbits/sec.

The HT capabilities are a little odd, I tried following
otus here -- in particular having SGI_40 but not SGI_20
is a little weird but afaict that's what otus does.
