This is really a 3-bit field, not a single bit,
so declare a mask and shift. Also fix hwsim, it
advertises the maximum possible.
While at it reindent all the defines using tabs
instead of spaces.

If the number of channels is > 1, which means that
hwsim will use mac80211 channel contexts, it can
also advertise VHT support.

Convert mac80211 (and where necessary, some drivers a
little bit) to the new channel definition struct.
This will allow extending mac80211 for VHT, which is
currently restricted to channel contexts since there
are no drivers using that which makes it easier. As
I also don't care about VHT for drivers not using the
channel context API, I won't convert the previous API
to VHT support.

As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.
Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.

Drivers (e.g. wl12xx) might need to know the vif
to roc on (mainly in order to configure the
rx filters correctly).
Add the vif to the op params, and update the current
users (iwlwifi) to use the new api.

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.

Allow drivers to indicate their mactime is at RX completion and adjust

RX_FLAG_MACTIME_START to clarify its intent. Based on similar code by

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.

To use mac80211_hwsim for testing channel contexts it
has to support them, and for that it has to support
hw scan and hw-remain-on-channel.
Since it's pure software, the off-channel activities
are really not off-channel but listening and sending
on a second channel. Also, the multi-channel isn't
really doing TDM, it's just on both channels at the
same time.
For testing purposes, you can specify the number of
concurrent channels with a module parameter, it is
set to one by default. When set to two or more, the
userspace API for wmediumd is disabled as it has no
provisions for multi-channel yet.

It is a frequent mistake to confuse the netlink port identifier with a
process identifier. Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.
I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.
I have successfully built an allyesconfig kernel with this change.

The code is fine in both cases as-is, but we can
write it slightly differently to fix smatch/sparse
complaints:
* compare the skb pointer (which we use as a cookie)
by casting the skb to unsigned long rather than the
cookie to a pointer (fixes "different address spaces")
* when transmitting, data->channel must be assigned,
don't check it (fixes "dereferenced before check")

Drivers need to report the number of transmission attempts for each rate
as well as to terminate the rate array with -1. The in-kernel datapath
of hwsim simulates a perfect medium, therefore the driver only needs to
report that the first transmission attempt was sucessfully completed at
the most favorable rate.
Rate control is working again for this driver. Tested mesh mode with
minstrel.

The queue mapping redesign that I'm planning to do
will break pure injection unless we handle monitor
interfaces explicitly. One possible option would
be to have the driver tell mac80211 about monitor
mode queues etc., but that would duplicate the API
since we already need to have queue assignments
handled per virtual interface.
So in order to solve this, have a virtual monitor
interface that is added whenever all active vifs
are monitors. We could also use the state of one
of the monitor interfaces, but managing that would
be complicated, so allocate separate state.

Generate more acurate tsf values in hwsim by setting the tsf value on
trasmitted beacons immediately before they are moved to the rx path.
Also, adjust the beacon timestamp to be the time at which the first byte
of the timestamp is transmitted.
With these changes the observed tsf offset between two hwsim/mesh peers
is 0 (unless the offset is modified via debugfs)

Not all devices are really capable of implementing
remain-on-channel, even if it is implemented in SW,
as they can't necessarily deal with channel changes
while associated.
Remove the WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL and add
it only if either the driver has remain_on_channel
implemented in the driver/device.
Also add it to all drivers that advertise P2P right
now since those definitely have to have it working.
