The NL80211_CMD_TDLS_OPER command was previously used only for userspace
request for the kernel code to perform TDLS operations. However, there
are also cases where the driver may need to request operations from
userspace, e.g., when using security on the AP path. Add a new cfg80211
function for generating a TDLS operation event for drivers to request a
new link to be set up (NL80211_TDLS_SETUP) or an existing link to be
torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these
events, e.g., based on noticing data traffic being sent to a peer
station that is seen with good signal strength.

In some cases, in particular for experimentation, it
can be useful to be able to add vendor namespace data
to received frames in addition to the normal radiotap
data.
Allow doing this through mac80211 by adding fields to
the RX status descriptor that describe the data while
the data itself is prepended to the frame.
Also add some example code to hwsim, but don't enable
it because it doesn't use a proper OUI identifier.

During testing our mac80211 driver a fatal error occurred which was
signalled to mac80211. Upon performing the reconfiguration of the
device a WARN_ON was triggered. This warning checked the return value
of drv_add_chanctx(). However, this returns -EOPNOTSUPP when the
driver does not provide the callback. As the callback is optional
better check it is defined before calling drv_add_chanctx().

When receiving Physical Link Completed event we need to create L2CAP
channel with L2CAP Create Chan Request. Current code was sending
this command only if connection was pending (which is probably
needed in channel move case). If channel is not moved but created
Create Chan should be sent for outgoing channel which is checked
with BT_CONNECT flag.

The core specification defines 127 as the "not available" value (well,
"reserved" for BR/EDR and "not available" for LE - but essentially the
same). Therefore, instead of testing for 0 (which is in fact a valid
value) we should be using this invalid value to test if the tx_power is
available.

Drivers are allowed to modify the sent skb and thus we need to make a copy
of it before passing it to the driver. Without this fix, LLCP Tx skbs were
not queued properly as the ptype check was failing due to e.g. the pn533
driver skb_pushing the Tx skb.

In some cases, pre-opened pipes don't stay open when a clear all pipes
command is sent. They stay created however. Therefore, one can never
assume that such a pipe is already open. As re-opening a pipe seems not
to be a problem, we do that now.

During hardware restart, all interfaces are iterated even
though they haven't been re-added to the driver, document
this behaviour. The same also happens during resume, which
is even more confusing since all of the interfaces were
previously removed from the driver. Make this optional so
drivers relying on the current behaviour can still use it,
but to let drivers that don't want this behaviour disable
it.
Also convert all API users, keeping the old semantics
except in hwsim, where the new normal ones are desired.

When the driver requests a restart (reconfiguration) it
gets all the normal method calls, but can't really tell
why they're happening. Call a new restart_complete op
in the driver when the restart completes, so it could
keep its own state about the restart and clear it there.

Parsing the P2P attributes can be tricky as their
contents can be split across multiple (vendor) IEs.
Thus, it's not possible to parse them like IEs (by
returning a pointer to the data.) Instead, provide
a function that copies the attribute data into a
caller-provided buffer and returns the size needed
(useful in case the buffer was too small.)

cfg80211: allow registering to beacons
allowed only a single process to register for beacon events
per wiphy. This breaks cases where a user may want two or
more VIFs on a wiphy and run a seperate hostapd process on
each vif.
This patch allows multiple beacon listeners, fixing the
regression.

In the current state the multicast rate can be specified on IBSS/MESH

When userspace asks to deauthenticate and we're just
authenticated (or still authenticating) send a deauth
frame instead of deleting the auth request.
On the other hand, if we've just disassociated and
therefore deleted all our state already, drop the
deauth request because we no longer have a channel
context to send it on.

Instead of using the pointer which can be re-used
fairly quickly due to allocator patterns and then
makes debugging difficult, maintain a counter and
use its value. Since it's a 64-bit value it can't
really wrap, but catch that case anyway since it
most likely points to a bug somewhere.
