tun: Fix/rewrite packet filtering logic
Please see the following thread to get some context on this
http://marc.info/?l=linux-netdev&m=
121564433018903&w=2
Basically the issue is that current multi-cast filtering stuff in
the TUN/TAP driver is seriously broken.
Original patch went in without proper review and ACK. It was broken and
confusing to start with and subsequent patches broke it completely.
To give you an idea of what's broken here are some of the issues:
- Very confusing comments throughout the code that imply that the
character device is a network interface in its own right, and that packets
are passed between the two nics. Which is completely wrong.
- Wrong set of ioctls is used for setting up filters. They look like
shortcuts for manipulating state of the tun/tap network interface but
in reality manipulate the state of the TX filter.
- ioctls that were originally used for setting address of the the TX filter
got "fixed" and now set the address of the network interface itself. Which
made filter totaly useless.
- Filtering is done too late. Instead of filtering early on, to avoid
unnecessary wakeups, filtering is done in the read() call.
The list goes on and on :)
So the patch cleans all that up. It introduces simple and clean interface for
setting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering
before enqueuing the packets.
TX filtering is useful in the scenarios where TAP is part of a bridge, in
which case it gets all broadcast, multicast and potentially other packets when
the bridge is learning. So for example Ethernet tunnelling app may want to
setup TX filters to avoid tunnelling multicast traffic. QEMU and other
hypervisors can push RX filtering that is currently done in the guest into the
host context therefore saving wakeups and unnecessary data transfer.

ipv4: Fix ipmr unregister device oops
An oops happens during device unregister.
The following oops happened when I add two tunnels, which
use a same device, and then delete one tunnel.
Obviously deleting tunnel "A" causes device unregister, which
send a notification, and after receiving notification, ipmr do
unregister again for tunnel "B" which also use same device.
That is wrong.
After receiving notification, ipmr only needs to decrease reference
count and don't do duplicated unregister.
Fortunately, IPv6 side doesn't add tunnel in ip6mr, so it's clean.
This patch fixs:
- unregister device oops
- using after dev_put()
Here is the oops:

mac80211: fix TX sequence numbers
This patch makes mac80211 assign proper sequence numbers to
QoS-data frames. It also removes the old sequence number code
because we noticed that only the driver or hardware can assign
sequence numbers to non-QoS-data and especially management
frames in a race-free manner because beacons aren't passed
through mac80211's TX path.
This patch also adds temporary code to the rt2x00 drivers to
not break them completely, that code will have to be reworked
for proper sequence numbers on beacons.
It also moves sequence number assignment down in the TX path
so no sequence numbers are assigned to frames that are dropped.

wext: make sysfs bits optional and deprecate them
The /sys/class/net/*/wireless/ direcory is, as far as I know, not
used by anyone. Additionally, the same data is available via wext
ioctls. Hence the sysfs files are pretty much useless. This patch
makes them optional and schedules them for removal.
