Only plain netif_schedule() remains taking a net_device, mostly as a
compatability item while we transition the rest of these interfaces.
Everything else calls netif_schedule_queue() or __netif_schedule(),
both of which take a netdev_queue pointer.

The lock is now an attribute of the device queue.
One thing to notice is that "suspicious" places
emerge which will need specific training about
multiple queue handling. They are so marked with
explicit "netdev->rx_queue" and "netdev->tx_queue"
references.

It can be obtained via the netdev_queue. So create a helper routine,
qdisc_dev(), to make the transformations nicer looking.
Now, qdisc_alloc() now no longer needs a net_device pointer argument.

A netdev_queue is an entity managed by a qdisc.
Currently there is one RX and one TX queue, and a netdev_queue merely
contains a backpointer to the net_device.
The Qdisc struct is augmented with a netdev_queue pointer as well.
Eventually the 'dev' Qdisc member will go away and we will have the
resulting hierarchy:
net_device --> netdev_queue --> Qdisc
Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue
pointer argument.

Probe responses shouldn't be encrypted, and mac80211 doesn't
set the crypto key accordingly. However it didn't set the
IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag which means drivers
could make an attempt to encrypt it, and causing a NULL
pointer dereference when accessing the provided hw_key field.

Currently the ieee80211_hw->workqueue is flushed each time
an interface is being removed. However most scheduled work
is not interface specific but device specific, for example things like
periodic work for link tuners.
This patch will move the flush_workqueue() call to directly behind
the call to ops->stop() to make sure the workqueue is only flushed
when all interfaces are gone and there really shouldn't be any scheduled
work in the drivers left.

This patch reworks the mac80211 debug settings making them more focused
and adding help text for those that didn't have one. It also removes a
number of printks that can be triggered remotely and add no value, e.g.
"too short deauthentication frame received - ignoring".
If somebody really needs to debug that they should just add a monitor
interface and look at the frames in wireshark.

This changes the RX path to no longer use function pointers for
RX handlers but rather invoke them directly. If debugging is
enabled, mark the RX handlers noinline because otherwise they
all get inlined into ieee80211_invoke_rx_handlers() which makes
it harder to see where a bug is.

The old infrastructure was:
- the default algorithm is built into mac80211
- other algorithms get into their own modules
The implementation of this complicated scheme was horrible
(just look at net/mac80211/Makefile), and anyone adding a new
algorithm would most likely not get it right at his first attempt.
This patch therefore builds all enabled algorithms into the mac80211
module.
The user interface for the rate control algorithms changes as follows:
- first the user can choose which algorithms to enable (currently only
MAC80211_RC_PID is available)
- if more than one algorithm is enabled (currently not possible since
only one algorithm is present) the user then chooses the default one
Note:
- MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n
Technical changes:
- all selected algorithms get into the mac80211 module
- net/mac80211/Makefile can now become much less complicated
- support for rc80211_pid_algo.c being modular is no longer required
- this includes unexporting mesh_plink_broken
