Conflicts:

The qmi_wwan merge was trivial.
The caif_hsi.c, on the other hand, was not. It's a conflict between
1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.
I did my best with that one and will ask Sjur to check it out.

When receiving an "individually addressed" action frame, the
receiver is required to return it to the sender. mac80211
gets this wrong as it also returns group addressed (mcast)
frames to the sender. Fix this and update the reference to
the new 802.11 standards version since things were shuffled
around significantly.

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.

ieee80211_set_disassoc() clears ifmgd->bssid before
building DELBA frames, resulting in frames with invalid
bssid ("00:00:00:00:00:00").
Fix it by clearing ifmgd->bssid only after building
all the needed frames.
After this change, we no longer need to save the
bssid (before clearing it), so remove the local array.

When a remain-on-channel item is deleted, we remove it
from the list and then start the next item. However,
if it wasn't actually the first item then calling
ieee80211_start_next_roc() is wrong as it will start
the first item -- even if that was already started.
Fix the two places that do this and add a warning to
prevent the problem from reoccurring.

In case the driver suspend callback fails, mac80211 is left
with stopped queues which prevents any further traffic as well
as all STAs are left marked with WLAN_STA_BLOCK_BA which will

undoing both before returning from __iee80211_suspend.

If an AP is beaconing with different capabilities than the one we get
in the associate response, we were still using the capabilities
received in the beacons. One example is when the AP is beaconing with
the short slot bit set to zero and then we try to connect to it with
long slot. In this case, we would keep using long slot until the next
beacon was received.
Fix this by using the correct capability value when calling
ieee80211_handle_bss_capability(). We were using cbss->capability,
but we should use the bss_conf->assoc_capability instead.

Some compilers (eg. gcc 4.4.1 for ARM) report a false positive warning
in mlme.c:
net/mac80211/mlme.c: In function 'ieee80211_prep_connection':
net/mac80211/mlme.c:3035: warning: 'sta' may be used uninitialized in this function
This is a false positive because the place where 'sta' is used is
inside an if with the same condition of where it is set:
[...]
if (!have_sta) {
sta = sta_info_alloc(sdata, cbss->bssid, GFP_KERNEL);
if (!sta)
return -ENOMEM;
}
[...]
if (!have_sta) {
[...]
sta->sta.supp_rates[cbss->channel->band] = rates;
[...]
For some reason the compiler doesn't understand this and warns.
While this is not a problem in the code itself, we can avoid polluting
the build logs with false positives by setting sta to NULL on
declaration and checking for sta instead of !have_sta in the second if.

This patch fixes the problem of dropping RANN element if the TTL
is 1. If the received RANN element TTL is 1 or greater than 1, the
RANN is processed. However, forwarding of received RANN element
with TTL 1 or less is prohibited according to the standard. This
is previously reported by Monthadar Al Jaberi.
Besides, this patch also avoid the processing of unicast PREQ
generation if the RANN element does not meet the acceptance
criteria mentioned in Sec. 13.10.12.4.2 of IEEE Std. 802.11-2012.

Some APs experience problems when working with U-APSD. Decrease the
probability of that happening by using legacy mode for all ACs but VO.

As defined in section 13.10.9.3 Case D (802.11-2012), this
control variable is used to limit the mesh STA to send only
one PREQ to a root mesh STA within this interval of time
(in TUs). The default value for this variable is set to
2000 TUs. However, for current implementation, the maximum
configurable of dot11MeshHWMPconfirmationInterval is
restricted by dot11MeshHWMPactivePathTimeout.

Stop connection monitor poll during disassociation.
This clears the polling flags and if a scan was
deferred it will be run.
Without this fix, if a scan was deferred due to
connection monitoring while disassociation happens,
this scan blocks further scan requests until interface
down/up which causes problems connecting to another AP.

In my redesign of remain-on-channel I forgot
that an item could be cancelled when it's a
dependent item that is part of another item.
Allow cancelling such items by removing them
from the dependents list.
Note that when we cancel the main item, all
its dependents are also cancelled. It would
be possible to not do that, but would need
tricks to promote an item from dependent to
top-level and is tricky in the HW ROC case.
