rfkill_switch_all shouldn't be called by drivers directly,
instead they should send a signal over the input device.

This patch removes redundant memset in rate scale. In rs_alloc_sta,
kzalloc is used so the memset can be avoided. In rs_rate_init, it is
a bug fix since it overrides everything set in other handlers namely

When we update the counters iff_promiscs and iff_allmultis
in struct ieee80211_local we have no common lock held to
protect them. The problem is that the update to each counter
may not be atomic, so we could end up with iff_promiscs == -1
in unfortunate conditions. To fix it, use atomic_t values.
It doesn't matter whether the two counters are updated
together atomically or not, if there are two invocations
of set_multicast_list we will end up with multiple
configure_filter() invocations of which the latter will always
be correct.

VLAN interfaces have yet another bug: they aren't accounted
for properly in the receive path in prepare_for_handlers().
I noticed this by code inspection, but it would be easy for
the compiler to catch such things if we'd just use the proper

Currently, we run through all three crypto algorithms for each
received frame even though we have previously determined which
key we have and as such already know which algorithm will be
used. Change it to invoke only the needed function. Also move

to be non-static.

This makes mac80211 pass all frames to monitor interfaces early
before all receive processing with the benefit that only a single
copy needs to be made, all monitors can receive clones of the skb
and if the frame will be discarded we don't even need to make a
single copy.

When an interface is registered it is still uninitialised so
ieee80211_if_reinit() can't be called on it (it will oops.)
Hence, we need to move the uninit method assignment.
Also, this patch fixes the bug that the master device is never
initialised nor deinitialised at all. Oddly, the deinit code
had an if statement to not run some code when running for the
master interface (which never happened), but that if statement
is also wrong. Fix that too.
Now that the uninit code is run for the master device, another
bug surfaced: it tries to remove all dependent interfaces and
that oopses or BUGs at some point, either because it unregisters
already unregistered interfaces (missing list_del bug) or due
to trying to iterate a list that has had other things removed.
Fix this too by handling the master interface specially.

Stateless NAT is useful in controlled environments where restrictions are
placed on through traffic such that we don't need connection tracking to
correctly NAT protocol-specific data.
In particular, this is of interest when the number of flows or the number
of addresses being NATed is large, or if connection tracking information
has to be replicated and where it is not practical to do so.
Previously we had stateless NAT functionality which was integrated into
the IPv4 routing subsystem. This was a great solution as long as the NAT
worked on a subnet to subnet basis such that the number of NAT rules was
relatively small. The reason is that for SNAT the routing based system
had to perform a linear scan through the rules.
If the number of rules is large then major renovations would have take
place in the routing subsystem to make this practical.
For the time being, the least intrusive way of achieving this is to use
the u32 classifier written by Alexey Kuznetsov along with the actions
infrastructure implemented by Jamal Hadi Salim.
The following patch is an attempt at this problem by creating a new nat
action that can be invoked from u32 hash tables which would allow large
number of stateless NAT rules that can be used/updated in constant time.
The actual NAT code is mostly based on the previous stateless NAT code
written by Alexey. In future we might be able to utilise the protocol
NAT code from netfilter to improve support for other protocols.
