This patch includes many places, that only required
replacing the ctl_table-s with appropriate ctl_paths
and call register_sysctl_paths().
Nothing special was done with them.

- The DNAT (Destination NAT) is not implemented in IPV4.
- This patch remove the code which checks these flags
in net/ipv4/arp.c and net/ipv4/route.c.
The RTCF_NAT and RTCF_NAT should stay in the header (linux/in_route.h)
because they are used in DECnet.

The file net/tipc/port.c takes a lock using the function tipc_port_lock and
then releases the lock sometimes using tipc_port_unlock and sometimes using
spin_unlock_bh(p_ptr->publ.lock). tipc_port_unlock simply does the
spin_unlock_bh, but it seems cleaner to use it everywhere.
The problem was fixed using the following semantic patch.

Some devices have a seperate LED which indicates if the radio is
enabled or not. This adds a LED trigger to mac80211 where drivers
can hook into when they are interested in radio status changes.

I would argue that mac80211 should handle fixed rates outside the rate
control code, which would also allow them to take effect immediately
instead of during the rate control callback, but this is pretty close
to correct.

This patch changes mac80211's Kconfig/Makefile to:
* select between the PID and the SIMPLE rate control
algorithm as default
* always allow tri-state for the rate control algorithms,
building those that are selected 'y' into the mac80211
module (if that is a module, otherwise all into the kernel)
* force the default rate control algorithm to be built into
mac80211
It also makes both rate control algorithms proper modules again
with MODULE_LICENSE etc.
Only if EMBEDDED is the user allowed to select "NONE" as default
which will cause no algorithm to be selected, this will work
only when the driver brings one itself (e.g. iwlwifi drivers).

This patch handles the reordering of the Rx A-MPDU.
This issue occurs when the sequence of the internal MPDUs is not in the
right order. such a case can be encountered for example when some MPDUs from
previous aggregations were recieved, while others failed, so current A-MPDU
will contain a mix of re-transmited MPDUs and new ones.

This patch adds the basic needed abilities and functions for A-MPDU Rx session
changed functions:
- ieee80211_sta_process_addba_request - Rx A-MPDU initialization enabled
- ieee80211_stop - stops all A-MPDU Rx in case interface goes down
added functions:
- ieee80211_send_delba - used for sending out Del BA in A-MPDU sessions
- ieee80211_sta_stop_rx_BA_session - stopping Rx A-MPDU session
- sta_rx_agg_session_timer_expired - stops A-MPDU Rx use if load is too
low

- struct sta_info: ampdu_mlme added to describe A-MPDU MLME per STA,

This patch makes a separation between Rx frame pre-handling which stays in
__ieee80211_rx and Rx frame handlers, moving to __ieee80211_rx_handle_packet.
Although this separation has no affect in regular mode of operation, this kind
of mechanism will be used in A-MPDU frames reordering as it allows accumulation
of frames during pre-handling, dispatching them to later handling when necessary.

This patch fixes a problem with rx handling on multiple interfaces. Especially
when using hardware-scanning and a wireless driver (i.e. iwlwifi) which is
able to receive data while scanning.
The rx handlers can modify the skb and the frame control field (see
ieee80211_rx_h_remove_qos_control) but since every interface gets its own
copy of the skb each should get its own copy of rx.fc too.
In my case the wlan0-interface did not remove the qos-control from the frame
because the corresponding flag in rx.fc was already removed while processing
the frame on the master interface. Therefore somehow corrupted frames were
passed to the userspace.
