Patch also takes care of disabling 11h when non DFS channels

This patch adds cfg80211 channel_switch support for mwifiex.
Upon receiving channel switch request, driver would parse channel
switch announcement IE from beacon_data.
If TX is blocked, netdev queues are stopped. IEs from csa_beacon
are then parsed and set to FW.

For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.
Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.
While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.
In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

This is really just duplicating the list of information that's
already available in the nl80211 attribute, so remove the list.
Two small changes are needed:
* remove STATION_INFO_ASSOC_REQ_IES complete, but the length
(assoc_req_ies_len) can be used instead
* add NL80211_STA_INFO_RX_DROP_MISC which exists internally
but not in nl80211 yet

A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.
This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

Auto TDLS functionality works as follows:
1. Whenever userspace application has triggered TDLS connection with
any peer, driver would store this peer mac address details in its database.
2. After this driver whenever driver receives packet on direct link,
it would store rssi and timestamp in peer information.
3. Whenever a packet is to be transmitted to non-AP peer in station mode,
driver would check if TDLS link can be established by looking at peer RSSI
information. Driver would initiate TDLS setup in such cases.
4. Periodic timer is used for updating peer information.
5. Auto TDLS peer list & timer are cleared during disconnection or driver unload.

pull request: wireless-next 2014-07-25
Please pull this batch of updates intended for the 3.17 stream!
For the mac80211 bits, Johannes says:
"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."
For the Bluetooth bits, Gustavo says:
"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."
and,
"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."
For the iwlwifi bits, Emmanuel says:
"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."
And for the Atheros bits, Kalle says:
"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.
For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."
On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.
Also, I pulled the wireless tree into this in order to resolve a
merge conflict...
P.S. The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

In managed mode if the driver is getting a re-associate command
from cfg80211, driver deauthenticates with the AP internally and
sends a disconnected event to cfg80211 before completion of its
association process. The disconnected event then modifies the
SSID length as wdev->ssid_len = 0. So, upon receiving the connect
result event from driver, cfg80211 is unable to get that BSS from
the device's BSS list and generates the following WARN_ON message.
WARNING: CPU: 0 PID: 857 at net/wireless/sme.c:658
__cfg80211_connect_result+0x3a6/0x3e0 [cfg80211]()
