The chip IDs are used all over bcma and no constants where defined.
This patch adds the constants and makes bcma use them.

I saw that when the watchdog triggers, the packets do go
through if we wait enough time. So we still have an issue
where packets are blocked in the Tx queue for a short while
and this needs to be debugged separately. For now, don't
restart the driver when it is not needed.

The dwell time for scanning is currently limited
so that it fits into the timings inside the ucode
when that is tracking DTIM/beacon periods for the
AP(s) it's connected to.
However, when it's connected to two APs, those
may be in lockstep, for example if they both have
a DTIM interval of 100 TU, then one could be 50
TU after the other, leaving only 50 TU free to
be used by scanning.
Since we can't know how far apart they are the
only option is to restrict to 1/2 of the minium
of the two APs.
In theory, it would be possible to not use 1/2 of
the minimum but take into account that if they
have different intervals then there will be a bit
more time since they can't be in lockstep, but as
they will have 100 TU intervals in practice that
complex calculation will probably just result in
hard-to-find bugs.

Larry (and some others I think) reported that with
single-queue drivers mac80211 crashes when waking
the queues. This happens because we allocate just
a single queue for each virtual interface in case
the driver doesn't have at least 4 queues, but the
code stopping/waking the virtual interface queues
wasn't taking this into account.

If the interfaces were removed just before a restart
work was started, open_count will be 0, and most of
the reconfig work will be skipped, including the
resetting of local->in_reconfig to false.
Leaving local->inconfig = true will result in
dropping any incoming packet.
Fix it by always setting local->in_reconfig = false
(even if there are no active interfaces).

Due to the way the default key links are created,
it happens that a link is left dangling:
* both unicast/multicast links are created
* unicast link is destroyed, and the links
are updated
* during this update, adding the multicast
link again fails because it is present,
destroying the debugfs pointer
* removing the multicast link won't work as
the pointer has been destroyed
Fix this by always removing the links and then
re-creating them if needed.

Until now, a u16 value was used to represent bitrate value.
With VHT bitrates this becomes too small.
Introduce a new 32-bit bitrate attribute. nl80211 will report
both the new and the old attribute, unless the bitrate doesn't
fit into the old u16 attribute in which case only the new one
will be reported.
User space tools encouraged to prefer the 32-bit attribute, if
available (since it won't be available on older kernels.)

Michal's monitor channel tracking introduce a locking problem
as it locked the rdev lock inside the netdev notifier which
isn't allowed as we might already hold it if we get there by
removing an interface that is up.
Fix this by relying only on the RTNL to protect the interface
counters, the RTNL is always held in these code paths anyway.

Some drivers require setup before being able to send
management frames in managed mode, in particular in
multi-channel cases.
Introduce API to allow the drivers to do such setup
while being able to sleep waiting for the setup to
finish in the device. This isn't possible inside the
TX call since that can't sleep.
A future patch may also restructure the TX retry to
wait for the driver to report the frame status, as
suggested by Arik in

IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there
is no current hardware supporting a rate chain with 5 multi

Implements .set_monitor_enabled(wiphy, enabled).
Notifies driver upon change of interface layout.
If only monitor interfaces become present it is
called with 2nd argument being true. If
non-monitor interface appears then 2nd argument
is false. Driver is notified only upon change.
This makes it more obvious about the fact that
cfg80211 supports single monitor channel. Once we
implement multi-channel we don't want to allow
setting monitor channel while other interface
types are running. Otherwise it would be ambiguous
once we start considering num_different_channels.
