on disassoc, ieee80211_set_disassoc() goes out of PS
before indicating BSS_CHANGED_ASSOC (not sure why this
is needed, but some drivers might count on the current
behavior).
However, it does it after sending the disassoc
frame, which results in null-data frame being sent
(in order to go out of ps) after we were already sent
the disassoc, which is invalid.
Fix it by going out of ps before sending the disassoc.

regulatory_update() just calls wiphy_update_regulatory().
wiphy_update_regulatory() assumes you already have
the reg_mutex held so just move the call within locking
context and kill the superfluous regulatory_update().

Cellular base stations can provide hints to cfg80211 about
where they think we are. This can be done for example on
a cell phone. To enable these hints we simply allow them
through as user regulatory hints but we allow userspace
to clasify the hint as either coming directly from the
user or coming from a cellular base station. This option
is only available when you enable
CONFIG_CFG80211_CERTIFICATION_ONUS.
The base station hints themselves will not be processed
by the core unless at least one device on the system
supports this feature.

This adds CONFIG_CFG80211_CERTIFICATION_ONUS which is to
be used for features / code which require a bit of work on
the system integrator's part to ensure that the system will
still pass 802.11 regulatory certification. This option is
also usable for researchers and experimenters looking to add
code in the kernel without impacting compliant code.
We'd use CONFIG_EXPERT alone but it seems that most standard
Linux distributions are enabling CONFIG_EXPERT already. This
allows us to define 802.11 specific kernel features under a
flag that is intended by design to be disabled by standard
Linux distributions, and only enabled by system integrators
or distributions that have done work to ensure regulatory
certification on the system with the enabled features.

While adding regulatory support to ath6kl I noticed that I easily
got the regulatory code confused. The way to reproduce the bug was:
1. iw reg set FI (in userspace)
2. cfg80211 calls ath6kl_reg_notify(FI)
3. ath6kl sets regdomain in firmware
4. firmware sends regdomain event to notify about the new regdomain (FI)
5. ath6kl calls regulatory_hint(FI)
And this (from FI to FI transition) confuses cfg80211 and after that I
only get "Pending regulatory request, waiting for it to be
processed...." messages and regdomain changes won't work anymore.
The reason why ath6kl calls regulatory_hint() is that firmware can change
the regulatory domain by it's own, for example due to 11d IEs. I could
of course workaround this in ath6kl but I think it's better to handle
the case in cfg80211.
The fix is pretty simple, use a different error code if the regdomain is
same and then just set the request processed so that it doesn't block new
requests.

commit "mac80211: unify SW/offload remain-on-channel"
moved the cookie assignment from ieee80211_mgmt_tx()
to ieee80211_start_roc_work(). But the latter is only
called where offchannel is needed. If offchannel isn't
needed/used, a uninitialized cookie value would be returned
to userspace.
This patch sets the cookie value when offchannel isn't used.

This patch is based on a user space (hciops) patch which never made it
upstream but does make sense to include in the mgmt part of the kernel.
(User space) commit message from Dmitriy Paliy:
"
Page scan interval in fast connectable mode is changed from 22.5 msec to
160 msec to perform less aggressive page scanning. This is done
accordingly to controller vendor recommendation.
Primary concern is that current parameters 22.5 interval, 11.25 window,
and interleaved scanning occupy whole radio bandwidth. Changing interval
to 160 msec should be sufficient for both speeding up connection
establishment and leaving space for other activities, like inquiry scan,
e.g.

This change addresses an L2CAP ERTM throughput problem when a remote
device does not fully utilize the available transmit window.
The L2CAP ERTM transmit window size determines the maximum number of
unacked frames that may be outstanding at any time. It is configured
separately for each direction of an ERTM connection. Each side sends a
configuration request with a tx_win field indicating how many unacked
frames it is capable of receiving before sending an ack. The
configuration response's tx_win field shows how many frames the
transmitter will actually send before waiting for an ack.
It's important to trace both the actual transmit window (to check for
validity of incoming frames) and the number of frames that the
transmitter will send before waiting (to send acks at the appropriate
time). Now there are separate tx_win and ack_win values. ack_win is
updated based on configuration responses, and is used to determine
when acks are sent.

Revert commit b78e8ceac23655e1e06b30aa95ab11742d1ac7c0
("cfg80211: track monitor channel") and remove the
set_monitor_enabled() callback.
Due to the tracking happening in NETDEV_PRE_UP, it had
introduced bugs because the monitor interface callback
would be called before the device was started. It looks
like there's no way to fix this, and using NETDEV_PRE_UP
is broken anyway (since there's no NETDEV_UP_FAIL), so
remove all that code, track interfaces in NETDEV_UP and
also stop tracking the monitor channel in cfg80211.
This mostly reverts to before the tracking, except that
we keep the interface count tracking so that setting the
monitor channel can be rejected properly.

This essentially reverts commit 2e165b818456 but
introduces the get_channel operation with a new
wireless_dev argument so that you can retrieve
the channel per interface. This is necessary as
even though we can track all interface channels
(except monitor) we can't track the channel type
used.

To call cfg80211_get_chan_state() we need to lock
the wdev, so we need to lock the wdev_iter mutex
in cfg80211_can_use_iftype_chan(). This needs to
use nested locking for lockdep.
Also, cfg80211_get_chan_state() doesn't actually
use the rdev, so remove that completely including
the lock assertion that isn't needed.

When drop_unencrypted is enabled and MFP is disabled,
non-robust management frames for not-yet associated STA are dropped.
This isn't visible as many management frames sent from the kernel
have TX_INTFL_DONT_ENCRYPT set and management frames injected
from a monitor vif have TX_CTL_INJECTED so aren't dropped.
But management frames sent from userspace via NL80211_CMD_FRAME
do not have this flag set, so are dropped.
This patch make it always accept non-robust management frames.

Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.
To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.
Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

Scan receive is rather inefficient when there are
multiple virtual interfaces. We iterate all of the
virtual interfaces and then notify cfg80211 about
each beacon many times.
Redesign scan RX to happen before everything else.
Then we can also get rid of IEEE80211_RX_IN_SCAN
since we don't have to accept frames into the RX
handlers for scanning or scheduled scanning any
more. Overall, this simplifies the code.
